In case you missed the #duocon livestream...

Hello everyone!

We streamed Duocon London 2019 live but some of you were not able to watch it then (it started at 9am London time). We will upload a better recording soon with clearer slides, but if you want to see the live stream replay now, as it is, you can watch it on https://www.twitch.tv/videos/484352859.

Check out the presenters and the schedule to help you find what you want to watch. Unfortunately, Eskeiver Robles could not make it, so Duolingo Head of Community JasonWaterfalls (aka Laura Nestler) was there to present her talk on some of our community efforts.

Another super cool thing is that one of our verified Twitch streamers Toastie202 was there and made a livestream on the ground/off-stage during our lunch break where she chatted with attendees such as David Peterson and Evan Edinger! You can watch that video temporarily here.

There were no livestreams of the Friday Kickoff party. But you can find some additional images under the hashtag #duocon on Instagram and Twitter.

We will make a fuller recap post once the videos are up permanently (as twitch videos are only up temporarily) and we have even more photos and footage.

Where do you think the next Duocon should be?

Events - Laura Nestler : Head of Community

Hey everybody.
I am the GAE team for today. I really wish he was here today. To tell you a little bit about the history, about how we've grown, about how we think about it.

Can you just raise your hand if you are a host in this room ?

Awwwwww, you guys. That's amazing.

Ok I'm going to talk to you y'all.

So when we started thinking about Duolingo Events we thought, ok, this makes a lot of sense. Right ?

Language learning is inherently social. And people generally are learning the language to speak it.
And yet the way the Duolingo ecosystem works you kind of have a one on one relationship with Duo. Which is fine.

But we thought, what if we found a way to expand our language learning ecosystem and create ways for these authentic micro communities to form in what we assumed people already wanted to do anyway.

So, about two years ago we launched Duolingo Events. ..... ... ........

This was very interesting. Thanks.


Presenter Q&A Panel (transcript)


Click here for a separate discussion on this. Māori coming to the incubator soon


So it looks like what goes into deciding what courses go into the incubator, is basically we just pull what's in Noah's brain, and then we put it into the incubator.

So, I'm pleased to announce, and please someone on staff correct me if I am incorrect about any of these.

Both Scottish Gaelic and Māori are entering the incubator, and are actually in the works right now.

I don't know how you do this !

We actually had teams already working on these courses, they just aren't entered into the incubator yet. They are working on spreadsheets. But just keep on watching.

There is more coming soon that we can't yet tell you about.



I wonder when there are more courses (not in English) in the incubator.


great! must have had fun


Yes I did ! The presentations ! And don't talk about that AMAZING party - including the discussions I was able to have. I even was able to have a chat with Luis ! And at the conference, some of the questions I was able to ask direct to staff, and also the other contributors, moderators and educators I met. You interact a bit different in person. As well as the revered learners I was able to chat with, and hopefully will keep in contact with 3 of them who are also so passionate about the mission of Duolingo, and have offered to help out.

I still have to pinch myself to ensure that this was not a dream, that I was by luck of circumstance able to sweep by and attend this 1st Duocon !

All I can say is keep watching this space, as things change and new resources and even more languages become available that expand and enrich all of our language learning experience.

And never doubt how each of you, as learners of language, are the stars of the show and the reason for Duolingo to be able to achieve its mission.

You are changing the world for the better of yourselves, your family (even if they do not care about language learning), the community around you, and thus the world around all of us.

Thank you for being inspiring !


DaKanga, you are awesome! Thank you so much for organizing this post and soliciting users to transcribe the presentations. In fact, the microphone sometimes does not allow me to hear what is being said (e.g. in the Presenter Q & A Panel). I'm sad I missed the first Duocon but hopefully next year will be more auspicious. It is great that due to your work, all of the DL community can view and study the Duocon presentations. Thanks again! Merci beaucoup!


You always are welcome my friend.
Also to see you sport your blue MOD tag.


Welcome to also being part of our diverse team of moderators, and I look forward to seeing you grace our moderator halls.

So my thanks also goes to you my friend. Merci beaucoup!


how many days shall a person be here to get a mod tag? Just curious.
what are the requirements? :D


Thanks for sharing these


You are welcome. It is also useful for my note taking, and also being able to reference things spoken about in Duocon, for when I assist others in the Forums and they have questions that are answered by these presentations.

And then also others can use this resource as well, to be able to assist others.

I should go and finish packing up my house here before I have to flip hemispheres again soon. There is soooooo much to do.


Transcript: (draft)

How is Duolingo Doing

Started 7 years ago, We wanted to do something that was related to education

People talk about how education brings equality to different social classes.
What I saw was the opposite. It brings people inequality. Because what happens is in practice, particularly in poor countries is that people that have a lot of money buy themselves the best education in the world. While people that don't have much money barely learn how to read and write. And because of that they don't get to make a lot of money.
So what we wanted to do was something that would give equal access to education
Another thing that I noticed growing up in Guatemala is how life changing learning English can be.
You live in a non English speaking country and you learn English your income potential improves.

... So we launched ....

(Currently their are about 30,000,000 active users. )

#1 Top Grossing Education App in the world.

This is something that we are very proud of.
And let me try to explain a little more about this.
When we launched the goal of the company really was, it is a very mission driven company. The goal of the company was to provide free access to language education to everybody.

But of course we also have to pay for the operation. It costs, today it costs, I don't know, 60 million dollars a year to run Duolingo.
So we have to pay for this. We have employee salaries, we have all kinds of things.
So, we had to figure out how to support Duolingo, but we didn't want to charge for actually using the app. So what we decided to do about three years ago is we decided to at the end of most lessons we decided to put a relatively unobtrusive ad at the end of every lesson. Fortunately as soon as we put that in there we started making quite a bit of money. Because we have so many users, that ad by itself makes us about 15 million dollars a year.

Soon after that we added a subscription, where the idea is Duolingo Plus, hopefully some of you are subscribers. Duolingo Plus, at the beginning, the main thing it did was it turned off the ads. Now we give you a few more things.

You can have access to the lessons off line, you can have a few things. But as soon as we added the subscriptions we started making more revenue from subscriptions than we do from ads.

We are relatively open about our finances this year. We are going to make a about 90 million dollars. 75 million is going to come from the subscriptions and about 15 million is going to come from the ads.

Now, what we are particularly proud of is that we are now world wide, we are the app that makes the most money in the Education category across all apps. But the thing is we are the only app that does not charge for actually learning. So, whereas every other app that is in the top grossing, in the app store, all of them charge for actually learning. You have to pay to use the app. In our case you don't have to pay to use the app.

You basically pay because you want to support us, or you want to turn off the ads, or you want to turn off the health system, or something. But you can always learn as much as you want pretty much for free.

And even though only about 2% of the people that are learning on Duolingo are paying subscribers, just 2% of our users paying it actually gives us more money than 100% of the users paying for using in every other app.

So we are very proud of that. And this is one other thing.

Yesterday I was talking to a few of you and people were worried that at some point we were going to start charging for education. And I told them that this is never going to happen. The reason this is never going to happen is not only is this part of the mission of the company, I whole heartedly believe this is a better business model. And the proof is we make more money than the other apps.

So I whole heartedly believe this is a better business model. Thank you.

I really believe this is a better business model for many reasons. This is what allowed us to grow. We have so far grown without really spending on marketing. In fact one of the interesting things is we launched our first marketing campaign ever. And this is after seven years of existing.

I am now going to show you some pictures soon. But basically in London we are testing some marketing we are doing. We are doing a few things. But we have basically been able to grow without having to spend on marketing because the way we grew people downloaded the app. They used it. They got a lot of value from it. And then they told their friends. So that is one really nice thing about our business model.

Another really nice thing about our business model is because we have so many free users we can actually use the data from all our users to actually improve the product. We have literally millions and millions of people using the app every day. And we use the data from the people to make the courses better, to make the product more engaging, and so because of that we basically have been able to continually improve the product over the last seven years.


I just wanted to say thank you for all the work you all put in here at Duolingo! You guys are always improving and you mission of free access to everyone in the world is absolutely amazing! I'm happy and proud to be a subscriber even if I lapse on it from time to time... I did want to just throw out a recommendation my nephew he is only 3 likes to help out with my lessons from time to time. But, I tell you what when you do the lessons with the pictures he absolutely loves that... It would be cool to have a way to just do pictures and you click it and it say the word in whatever language your learning. It would be great for the really little ones :)

  • (Re)Connect: Heritage Languages and the Internet Noah Buffini Higgs | NoahHiggs

    How are the needs of minority and heritage languages addressed by online resources? How might their needs be affected by and change due to how we use the Internet? Noah is an Engineering Master's graduate who is also a Course Contributor on Duolingo's award-winning Irish team.


Hi Guys, Thanks so much.

Hi everybody.
I'm delighted to be here.
Thank you so much to Duolingo for having me And I'm glad to see such a turn out in the room.

My name is Noel Buffini Higgs And I'm going to try my best to follow that

And talk to you about Heritage Languages and the Internet as a place to promote, preserve and progress them.

So let's check it out.


10 minutes to acquaint ourselves ...

  • The Irish language
  • Education on line
  • Challenges facing minority languages
  • Existing plans
  • How the internet can help

There's a lot to get through ideally, And we might have to be a bit discerning as to what we get through, and that is why we have the questions at the end. And there is the "In Depth room", is it called. So there will be time for everything. But I don't want to boggle peoples minds

It's a bit of mind boggling topic. (... check transcript here... )

But we might get to do a little intro to the Irish language, just for some context.

To give you a bit of a background from where I'm coming from.

And looking at Education on line Which I am sure you are all pretty well versed in. Welcome to Duocon.

But then setting up what are the challenges facing minority languages specifically.

Identifying those so we can move onto what we can do about them.

And then specifically about how the internet can help with that.

So, why am I talking to you about this.

My Perspective

  • Raised in Dublin by English-speaking parents
  • Master's Mech. Engineering
  • Gaelscol student. Loving Irish since c.2012 (mid teens)
  • Give private Irish course
  • Duolingo course builder

My background is I was raised in Dublin by two English speaking parents, like most Irish people.

I'm not sure how aware people are of the Irish, and the Irish situation. I would be a typical example of it, in that we have some knowledge of it, but my household is English. In fact my Dad was American And like most Irish people my Mother was exposed to Irish in the Education system. It's one of the mandatory subjects we study from the age of 5 to 18. But she is a typical case in unfortunately she never really connected with it. And left with kind of mixed feelings and incomplete knowledge maybe.

I myself had the privilege of attending an all Irish school. My education was completely in Irish till I was 18 and that was a big help, just for exams. Even if you didn't care. But I care, because I connected with it in particular

That happened around my mid teens. And it was a pretty deep rabbit hole. And it spiraled until eventually I was applying to Duolingo and got it. Yeah. And haven't looked back. So it's been a really rewarding few years.

And I want to talk to you about what we do, and what could be done. And to get the discussion going.


Irish on Duolingo

  • Taught word-by-word
  • Words taught in sentences
  • Grouped into topics, presented in lessons
    (Display of incubator screen)

So Irish on Duolingo.

We're all pretty well versed in this. Just for maybe for the the creators, and if anybody was interested and didn't know too much about how it happened in the incubator. It's nicely designed and like it is like a nice place to work.

But Duolingo as we all know presents the language to you word by word.

And our creators we are required to create a minimum of 3 sentences per word when we first introduce it for the algorithm to consider it learned.
And obviously hopefully it will show up in the course again after that.

The word is always presented in the form in a sentence. Because Duolingo don't want to show you abstract grammar. They don't want to bog you down with all the nitty gritty And they want to get you to be using the language. And I will get to this later, but I really love that.

And then we group them into topics, so there is a coherent theme going on and your not just learning them like anything in a given moment.


And later I will show you an example where we are teaching "gaelge"which is to mean or have a sense. Which is a really useful thing to teach a learner early on. And to this we added six sentences to this one, as it was kind of an important example.
Just a moment, I have to look at my time here, otherwise I am going to ramble. Yeah.

So. The sentence we are looking at here is "Cad a chiallaíonn sé seo." What does this mean.

Which is a really useful thing to teach a user early on. We tried to focus on this skill early on because, obviously. I'm going to have to stop myself from referring back to Gabriela's talk from earlier on (Gabriela Talarico : Shameless: A Tale of Linguistic Acceptance ) . But it said so many things that I am going to talk about throughout the talk.

One thing she pointed out is it is tough, and you need the skills to ask for help. That sounds a bit heavy, but I mean in terms of a language.

Okay, So, anyway.

Let's look at what the challenges are facing Minority Heritage Languages in particular are, so that maybe you can have a few ideas in how to address them.

But first I just want to clear up what I mean by Minority and Heritage languages. I know there are a few definitions around. And I'm not expecting everyone to be an expert on it. And I had to look up these terms myself.

But First! Definitions

Minority Languages

  • A language spoken by a minority of the population

Heritage Languages

  • Learnt by its speakers at home as children, but never fully developed because of insufficient input from the social environment (Valdés G. 2000) Connected to a culture/tradition.

  • is a minority language (either immigrant or indigenous) learned by its speakers at home as children, but never fully developed because of insufficient input from the social environment: in fact, the community of speakers grows up with a dominant language in which they become more competent.


So minority language is easy enough. A language spoken by a minority of the population.

Heritage language is a little more nuanced. I found a few definitions. And this is what I chose to go with.

Its language learned by its speakers at home as children. And there is a little asterisks there that I will return to. But the point is, never fully developed because of insufficient input from the social environment.

And that is the challenges a lot of these languages that aren't the dominant language in their social context. And people may not know that much about them. And it is a bit of a snow ball effect.

I'd like to add to that that they are attached to a culture and tradition. Like probably most languages. And it is just worth pointing out that it is kind of symptomatic of different cultures which maybe struggling against each other as time marches on.


Just quickly for the for the at homers. Just to chill and points ...
I give a lot of lessons back in Ireland and a lot of people come to me already as adults. And like my mother and a lot of people even now. But especially in generations gone by. They didn't fully connect with the language. Even though we in Ireland have the privileged that it is recognized by the state. A lot of people did not get to be raised in Irish. And that is the problem that we are trying to combat.

So I would like if people like that that are connecting with the language consciously as adults that we are not excluding them from this definition.

That is just a small point. Just keep in mind people are trying in whatever way they have at hand to become involved in these languages, and we are trying to make that as easy as possible.

Okay. So basically bringing it back here. So what we are talking about is Languages other than the dominant languages there in the social context.

So in Ireland that would be Irish that we are trying to promote. In a country where most households speak English.

So. What are the challenges particularly are there for these Minority Languages ?

And why can things be so difficult. Or seem so difficult at least.

A huge one on the first one I want to point out :

Is Stigma

So there is a lot of literature out there about language ... Languages will compete against each other in a social context. And like people a hierarchy will develop.

And so you will slowly have people, especially when it is a Minority subject in school actually, who are kind of pushed to these classes. They may develop this sense ... where it is a responsibility and its a big effort. And they may ask themselves "Why the hell am I doing this ?" "What's the point ?"

And obviously that's a frustrating thing for people in my position to hear. But I can't blame them. People are highly practical. There are only so many hours in the day. And there not always the most patient.

But they might wonder like. If I have a language that already suits me for business, and I can get an international diploma, and I can travel with it. Why am I putting so much effort into reinvest into Irish now ?

It's actually really handy that Dave (David Peterson : The Value of Language ) just went there. Because he pulled apart all the reasons why language can be really full and fulfilling on its own. I might touch on a few of them in a second.

But the point is that most people are not of that mind set.


And I hear so often back in Ireland "It's a dead language." "It's on the way out." It can be very doom and gloom. And that is just the main thing that you find yourself struggling against.

Another one is that languages are just all different. Particularly you might notice a trend if you look at minority languages around the world that their some of these quite odd ball languages and family groups. You find like how history happens.

So some of the more dominant languages are a bit more closely related to each other. So like English is a big language. And if someone wants to learn German tomorrow, its different. But a lot of things will make sense to me quite quickly.

Its not like Irish is. Now Swedish the word order would not be the same. As if language learning was not just already a big investment of my time and effort. These minority languages, they are just kind of a bit of a co-incidence. But the trend is that they can be really different.

Like Hawaiian, like Māori. Like Welsh and Irish. There is just very little you can grasp and hold onto in the beginning and make it attractive to have a go. It seems like tall stairs right at the beginning.

Numbers of speakers.

There is a bit of a catch 22 that happens when a language becomes a minority language. Because it is not in peoples faces. You don't become exposed to it frequently. And people can spend most of their lives not having to think about it that much.

So the speakers that are still around as well can experience a problem where maybe they don't ... sorry I have to keep going back to myself as an example, but I am hoping that it is generally applicable to people.

If I walk through Dublin tomorrow. The statistically one in four people can hold at least a basic conversation with me in Irish. My big problem is I don't know where they are or who they are. And it might sound weird, but it is considered very rude to just walk up to somebody and start speaking in Irish. Because of some of the stigma against it.

I'm never going to walk up to anyone and be like "Conas tá tú?" (How are you?) They will be like just get out of my face.

So I don't know where these speakers are. And then that can just be a vicious circle. And the few of us that are, we just dwindle and fade out into the background. And everyone just moves on with their lives. And that is kind of how it can feel.

So these are big problems. And they are not that easy to fix.

So this talk is just about getting the discussion going. And progressing things. But it is going to be hard.

Challenges for Minority Languages?

  1. Stigma
    -"Not required" in everyday life
  2. Strange
    -Difficult. different
    -Lack of understanding
  3. Numbers
    -Speaker numbers low
    -Distribution spread out
    -No community outlet


We can look at some things we can do.
Firstly, what can be done already, and is off the internet.

Well, certain languages are looking to enjoy a certain amount of national recognition. Welsh as been this way. Irish is this way. Māori I hear is recently like this, so I'm really proud of them.

You'll see things like Government schemes they'll be funding from central Government. It'll be in the public education system, at least to a certain degree. Their'll be awareness weeks. People are encouraged to use the language in business and put it on sign. Which is cool as it kind of addresses the problem of just get it in front of peoples faces. Get them a little bit familiar with it. Have a few phrases that people feel like a little bit it belongs to them. They have some sort of authority over it.

Other languages unfortunately might not enjoy the same centralized support from their home government. And I am not aware of any central funding from the U.S. for the Navajo language for example. And there are a lot of endangered languages in the U.S. So I don't even know how they would begin to prioritize.

But say for example they can't get Federal support, the locals. The Town Councils, the County Councils. Whoever got the funding for the Navajo Nation as one example. Or Arizona State. On a smaller scale they can try to get people together and do similar schemes. And try to get it into education. Or an elder or someone that is good at speaking the language into the classroom. And they might also organize their own awareness week.

And it's important to realize that it is no less effective than the Government schemes on average. It is just that your not reaching as many people. But its a different context.

Currently being done:
1. Welsh, Māori, etc...
-Government schemes, public education, awareness weeks
2. Navajo, etc.
-Local scheme, community driven

How can the internet help (more)?

How can the internet help to progress this ? And I put in brackets there How could it help even more. Because, once again, welcome to Duocon. We're already using the internet to teach people languages.

But I think, if I may say, I think the internet is still in its infancy.
And that I think you may agree, and that is why we are here discussing it.

So how can we even better leverage the internet and its strength to get language education going?

There's so much potential!

First thing I'd like to point out is a big one.


As in personalization.

Cookies kind of feels like a bad word these days.
Like this I feel is like a metaphor for us.
He doesn't know what in the hell is in those cookies.

But he's eating them. And in fact he can't stop.

I don't know whose watching me on youtube. Or what their gender is. Or exactly what information they are gathering about me. Or what their going to do with it. But that doesn't stop me consuming the internet stuff. So it feels a bit bad. It's kind of unfortunate that the advertisers monopolized that word first. I guess they were the most ambitious ?

But that doesn't mean that we as educators can't leverage cookies and personalize peoples experiences for their language learning, just because of that.

Let me give one example of an experience.


  1. Cookies!
  2. Forums
    -networks, discussions
  3. Anonymity

The List Goes On!

  1. Casualness
  2. Economy of experts


What are we trying to achieve?

  • Promote!
  • Reconnect!
  • Enjoy!

Go raibh míle maith agaibh! : Thank you!

This link will take you to the same place but will avoid the 36 minutes and 23 seconds of waiting for the talks to start



Great! Edited the post link =]


It was great to watch the presentations having been unable to go after all as I had to work that day. It makes me sad that it didn't work out but at least I know what went on.

It is great to see all the new exercise types being worked on. I really look forward to those.

If I had been there my top suggestion for an addition would have been to add tts in both directions as an option for people who are doing courses which don't include their native language. I suggested this before and I did catch it being tested for a while but nothing came of it but it would be a really good add so I want to out it out there again. Often different language combinations have different vocabulary but it is harder to absorb the new vocabulary when you can't hear it spoken, this feature would make more efficient use of content already available.


Wonderful! Thank you vivisaurus. Such cute photos and nice videos! I'm so bummed out that I couldn't attend DuoCon. Suggestion: can admin find an outlet to sell any leftover swag? I want that green Duolingo mug! =D


Hi everyone at Duolingo. Just to say a big thank you to Duolingo and everyone that organised Ducon. I am new to the app and came across the conference by chance. I signed up, almost didnt go on the morning but I did and thoroughly enjoyed it. It was super interesting and fun. I am not a huge networker but I did have a brief chat with Noah who changed my mind on heritage languages and now I am signed up for Irish too. I wish it could be in London every year but where ever it is next year, I would definitely consider attending. thanks again. Bryan


My friend and I both had an absolute blast at Duocon! I'm so happy to have met you daKanga and other Duolingo reps, and to have mingled with other users like myself. It was just so welcoming and educational, I'm so glad I went. That Kick-off Party, my god, what a crazy fun time! And the post-conference mingling/drinking/karaokeing! I still can't believe it happened haha! Looking forward to next year, wherever it may be :)


What a blast to also get to meet you CafeAuJay !
I am sad I missed out on the karaokeing.

Though so glad I was able to experience many other activities.

I also look forward to continuing to see you around and about.

And also perhaps more empowered and motivated to do that bit more, when time and resources allow, that help make all our lives better.


How about having the next conference in Pittsburgh?


Nice! Will you be able to announce the next DuoCon further in advance? I'd love to go! I'm based in London so was able to go this year luckily and really hope I can go next year! I had a great time! :D


Would also love to see some more activities, similar to Runefest if anyone has ever been to that? Will DuoCon always be free too? Runefest charges £150 per ticket which I sadly won't be paying. I hope DuoCon never charges that much!


why do you learn so much languages wow-


I didn't know about this! Thanks so much for sharing!


Thanks so much for this event, Duo team! I was really impressed by the quality of the whole weekend. Everything ran so smoothly, the staff were unfailingly friendly and welcoming, the talks were interesting, and the food was fab.

I've blogged about my experience of the event here: https://somethingaboutleo.blogspot.com/2019/09/duocon-duolingos-first-conference_24.html. I just wanted to say thanks for all of your hard work.

I can't wait to be at Duocon 2020, wherever it happens.


Heads up to everyone on this thread that we have announced where the next Duocon 2020 will be. Check out this forum thread.


Your next DuoCon should be at Area 51, so not only can we have another raid, but so we can actually make use of the goshdarned September 20th date.


Thank you for this heads up !
You are GEM :D


I think you should have a duocon in California. I know many people here that use Duolingo!


Proud, when I see Malaysia in one of those pictures.


Thanks so much for this. I would have loved to attend Duocon. I just watched the section on learning initiatives and am so excited! As an ex languages teacher and mother trying to motivate her son to use Duolingo every day, there were lots of ideas that I've been thinking about for some time. So, so good to hear about what's coming soon. The podcast wasn't mentioned (as a current language tool currently available), but I've listened to the Spanish one and I think it's wonderful too; reminds me a bit of This American Life. It's a fantastic listening tool. So thanks for everything and I'll keep plugging the app; it's parents' evening soon, so I'll be harassing all the language teachers :)


I wish I was able to go :/, it sounded like a lot of fun!

Keep up the great work duolingo! Love you guys :)


Great progress duolingo! Keep it up :)


It brings me great sadness that I was unable to be there....I mean...I couldn't have made it anyways (as I am not 18 years+)..but to see all of the fun you guys had...what there was to take away from the conference...and the experience on the whole....man, you can't help but feel a little jealous!

But overall...heads up to the #duocon team and all who streamed it, spoke it, and experienced it. Hopefully we get to see many, many more of these duo conferences! Duo 32



I think it is so awesome that we have a chance to learn any language of our desire. What we can also do is take advantage of it and a lot more things other basic school stuff. And not everyone gets a shot at something like this.

With Great Love, Abby


hey new here having fun with duolingo


Thank you so much for sharing this! What a wonderful company. I have been wanting to learn German for so long, and this is helping me greatly. I am a music educator and took Italian and French in college, but was unable to take German. So grateful for this course and these founders!


That's awesome I wish I could have been there!!


Please can you set up the wonderful stories for Welsh. The French ones are so helpful......pretty please????


Thank you for making this- was a good comment.


I FINALLY got a chance to watch the stream. It was almost as good as being there! I am so thankful that it was recorded.

And Lin, thank you for all your reporting of the event.

I love it! Duo has become a great community, can't feel son amazed about the popularity and growth that this website has developed over the years- It's been seven years now learning and although this was not my main learning method I admire the work you've put on this guys. I will be looking forward the streaming!
