Weekly Incubator Update: Tracking Progress from August 16th to August 23rd

Two new courses
Welcome to the "Portuguese for French" and "Italian for Portuguese" teams who have just started in the incubator. And they both have started with a big bang, with 14% and 10% progress respectively during the first week! Who would have thought someone from the German wing of Duolingo would also contribute to the Italian for Portuguese course? :) That is polyglotism! And we see so many examples of that in this forum!

Faster progress
Team "Catalan for Spanish" is also making some kick-ass progress. The overall progress is not that top heavy as this might suggest - we have a healthy median of 'one'. As a result, the average has exceeded 'two'. It is hard to recall when was the last time I saw such a high overall average progress.

Thought for the week
Fast pace at the incubator and new courses coming to beta soon!

Hello Duolinguists! It's been a while since our last official update! The last few weeks have been a very exciting time for our Korean->English team, now that our newest teammates cisnb125 and Croesus1983B have joined us! We are hard at work to improve our English for Korean speakers course so that we can graduate from the Beta testing phase. As we continue working, please keep using the course and report any issues your find! Of course, this doesn't mean report every time you personally are having a hard time, but when you find a mistake in the course itself. Our number of incoming reports still has some room to fall before we can graduate from beta, so we hope that you'll continue put some care into sending us your reports.

Course stats:

(After the addition of report function to the mobile app our report numbers increase, but thankfully the numbers are steadily making their way back down ^^)

Report rate: 4.07/100 users as of 2015.8.18 (~3.50 on 2015.6.18)

Total number of reports: ~3,496 as of 2015.8.18 (~29,222 on 2015.6.18)

Send us your careful reports!

Thank you for your patience and your understanding! Also, thank you for your support of the English<->Korean team as we continue to do our share in making this free language course to increase access to education around the world.

Thank you!

100K Learners, Celebrity AMAs and more

This has been an incredible week for our Esperanto course. This week we saw our 100,000th learner sign up! Every day we keep seeing new posts from our learners who are completing the tree, some even with a completely golden tree. What dedication!

We decided to liven up the community by offering a series of AMA (Ask Me Anything) sessions with Esperanto celebrities. On Friday, we had the chance to meet Bertilo, the rock star grammarian himself. Our next guest will be the popular YouTuber, Evildea. See the complete AMA schedule.

In other news, I was recently at the Internacia Junulara Kongreso in Wiesbaden (Germany) and met four people there who started learning Esperanto on Duolingo. After just two months of learning, we were already having conversations together. What an incredible experience! I also heard about one of our learners who showed up at one of Berlin's Esperanto clubs (we have five here) where he spoke Esperanto the entire evening.

We were also excited to discover that toward the end of the Esperanto tree, around half of the sentence discussions are even in Esperanto. I haven't heard of this happening in any other course. We're blown away by our amazing learners, our great team of course contributions as well as the excellent support we get from Duolingo HQ. Congratulations everyone and keep up the great work!

Week 7

Now at 290 words, 8 percent. We are trying to figure out ways of letting new people who do not have that much time contribute to the course.

Week 11: 18% complete, beta launch 10-Dec-2015

The research on the tree design is actively on, but yet again, no progress to report.

TL;DR A boosted progress at the incubator this week - 2.04% and two new courses started - "Portuguese for French" and "Italian for Portuguese".

The next update is expected on Sunday, 30th of August at 3:00 pm UTC.

Я хочу русский язык! Vote up if you are also waiting (im)patiently for Russian :)

August 23, 2015

It would be great if someone from the Russian team could made us a quick briefing. Thousand and thousand people are waiting the result of their amazing work ;-)

August 23, 2015

I think you can assume that it's mostly out of the hands of the Russian team by now and waiting on duolingo to finalise their preparations. It's really normal for there to be a one or two month wait after a course shows at >97%. I haven't personally worked on a course but it's my understanding that once a course goes live it is very hard to change or correct some things so they want to make sure it's really ready to go.

I personally wouldn't imagine we will see the Russian course début in August and, while September is likely, I also wouldn't be surprised if it doesn't happen until October. This is a really important course for duolingo and so I'm sure they want to give it the best start possible.

August 23, 2015

From my understanding, it's usually a month after a course hits 100%. So we probably still have at least another month to go, since they're not at 100% yet. :-(

August 24, 2015

As far as I know, there's a little bit of work to be done, but right now they're dealing with issues getting a TTS.

August 23, 2015

Unfortunately when people ask, the result is mainly snarky responses to discourage people from asking questions. :-/

August 23, 2015

Check out the first post here:

August 26, 2015

I hope this is the month long delay and when it reaches 100% it'll be released.

August 23, 2015

It's soooo close...

August 23, 2015

Andrewr756, I'm glad this is the top comment. I came to the Discussion Forum today specifically to find out why the Russian Course has been stuck at 97%, and the completion date keeps getting pushed back. It was scheduled to be done by Aug 25, then Sep 1 and now Sep 7. The delay doesn't bother me but I hope it's done by January -- that's when I plan to start it. I'm really excited to start learning Russian. Thank you Russian Team!

EDIT (a few hours later):

I just noticed that within the last 5 hours Russian moved from 97% to 98% complete. !!! And the projected launch date moved up 3 days to Sep 4.

August 24, 2015

The thing you need to remember with the estimated completion date is that it is purely an automated date that only takes into account how much of the tree has been completed. It ignores tree versioning (ie Russian needs skills to cover six cases, an alphabet, etc), the search for a TTS, writing notes, proofreading sentences, varying availability of the course creators, etc.

It's pretty much never going to be accurate. Which sucks, and I'm honestly not sure why Duolingo puts a date up they know to be wildly inaccurate, but basically the date is nigh on meaningless, and that's a big part of why it keeps changing. It's not someone at DL deliberately being awkward, or Team Russian reneging on a promise, it's purely the product of an automated system making a highly flawed guess.

August 24, 2015

Thanks. Yes, I figured it was automated. The estimated completion date seems to be about 2 weeks out, based on what still needs to be done. If nothing new is done on a particular day, then the estimate moves one day forward keeping it at 2 weeks.

It would be nice if it's done by January but if not then that's OK too. I need lots of practice with the other 3 languages I'm learning. Or I could start studying Russian with and get a head start.

August 24, 2015

I've heard good things about, but I'm curious a to how far one can get with (more or less) just the upcoming Duo course, so I've not used it... But then again I don't have an upcoming deadline like you do.

I agree with flootzavut that it's a bit strange that Duolingo chooses to publish a date that is so inaccurate and keeps changing so wildly, but I guess changing it into something less exact but more truthful is not a high priority for them.

August 24, 2015

Yes, I'm waiting for Russian... in the meantime, I'm battling a seemingly endless degilding under my German tree, and if I have time after that, maybe doing some French.

I guess that the up side to having to wait for Russian is that by the time they get to 100% and we wait around for a month of them at that level... the manic coloring spree going on in my German tree should have calmed down a bit by then.

August 24, 2015

I'm waiting for it. And about the release date, I don't think we'll have to wait another month after Russian reaches 100% Seems like actually the tree is almost done and now they're redoing some skills of the beginning of the tree while waiting for the TTS voice. So I think the release date depends more on Duolingo. I don't remember this being the case with other previous courses. Usually they finished the tree and had this ''big delay month'' after reaching 99% This makes think that this 97% is actually more like the 99% of other courses. But anyways, those percentage numbers are not very accurate and I feel like people are obsessing over them too much without considering other factors for the release date. Some even think that the course hasn't made any progress at all in the last month which is not true.

August 24, 2015

Team Hebrew still going strong!

The Catalan for Spanish and Portuguese for French teams must have got some polyglot aliens to speed up the courses, but Team Hebrew should be recognised for getting for than 1% every week for loads of weeks in a row! :)

(I think I'm being bias here...)

August 23, 2015

We have to admit it... We have hired the same Catalan aliens that are able of things like these:

If you can construct a human towers ("Castell") of ten levels, what is a simple course preparation? ;P (Just kidding, it's actually a lot of hard work)

August 25, 2015

No, it is actually Czech which has done 1% for 4 weeks. Hebrew did some skipping.

EDIT: you mean over 1%. That makes more sense.

August 23, 2015

Hebrew and Polish, the 2 language that I have to learn...

August 25, 2015

I'm really excited for Czech for English. Prague is a really important city for me (it is where I fell in love with my other half) and I'd love to be able to return for a third time with an ability to speak some of the language. Got my fingers crossed the steady progress continues for as long as possible. Thanks to those putting in the time for this. :)

August 23, 2015

TL;DR The usual movers moved, and the usual stayers stayed.

August 23, 2015

No comprendo

August 26, 2015

Lots of very interesting news this week! You've outdone yourself jitengore. For teams Russian, Vietnamese and Hindi for English, I wish you all the best ! спасибо, cam on, धन्यवाद !

I hope to ride the trans-Siberian railroad some day, and figure out how to get on and off and not to miss the train, so Russian is really high on my list ! My fantasy is to get on board in St. Petersburg with a case of vodka, a case of caviar and War & Peace, and ride to Vladivostok. The vodka should loosen the tongue so I can engage in long conversations on the long train ride across 11 time zones !

Following the WIU each Sunday morning fuels my dreams ! What are your language dreams?

August 23, 2015

I'm going to take the trans-Siberian railroad to Moscow, take a train to Kiev, then to Poland, then take a train back to Beijing(the world's biggest hyper loop station at the time) and to Jerusalem. I hope we meet!

That was a little weird, but I am just dying for a trans-Siberian railroad so I can have the ultimate road trip.

August 25, 2015

Catalan for Spanish is doing even better than last week... this was a good week for the incubator. If only Romanian for English speakers could get past the roadblock they're currently at...

August 23, 2015
  • 1388

Yesssssss! Me too, I am waiting for Romanian and Catalan!

August 23, 2015

I wish team Hungarian made a report about what's going on with the course.

August 23, 2015


August 24, 2015

Could we please get an update from team Russian? I don't mind the wait, but I am growing discontent with the long silence on the incubator page while a lot of people were getting their hopes up that the course would be released by the beginning of this month.

August 23, 2015

The Russian course just changed from 97% to 98% complete, so something's going on.

August 25, 2015

If I remember correctly, they made a post when they were around 80% for questions to answer in their next update, which was possibly at 85%, but they never made another update... :{

August 24, 2015

Are you talking about the FAQ they did in their 2/3 update?

August 24, 2015

Not sure, but I thought that they were gonna do another update at around 85%.

August 24, 2015

I'm waiting for Russian and Catalan! <3

Fixed with lingots for spotting and reporting :)

August 23, 2015

I realized that there is /comment/ between and everyone's username. None of the links to users are working. If the comment/ part is taken out of, then will work.

August 23, 2015

Great catch! Something must have changed with how the pages are rendered. It seemed that the "/" before the username was not required in the mark downs, but now it seems to be required. I will keep that in mind in future.

August 23, 2015

Working perfect now, cheers!

August 23, 2015

The last 5% takes time :p

August 23, 2015

I believe there was an update from team Italian for French.

August 23, 2015

Oh yes, I thought I had covered all the phase 2 courses.... Adding it now! And thanks! :)

August 23, 2015

Post some love for team Hebrew!

August 24, 2015

Thank you team Hebrew! I did not realize you were working on this course, and it's one of the languages I want to learn. Thanks so much.

August 26, 2015

Go Polish! Steady progress over the past month, I'm happy.

August 24, 2015

This week again the catalan team has been the best on growing !!! Congrulations !!

August 23, 2015

Nice work Portuguese for French speakers Team! Team Polish - I believe in you guys, keep up your wonderful work!!! :D

August 24, 2015

I read somewhere that one of Duolingo's requirements for building a course is someone volunteering to moderate the course's forum. Is this true?

If it is true, it would mean that even if a lot of qualified people volunteer to build a course, and even if the Duolingo staff have time to help them out, Duolingo still won't add the course to the Incubator.

How could a volunteer prove his or her qualifications for moderating, for example, a forum for a Maori for English speakers course on Duolingo?

  • If he or she is seriously into Duolingo and likes several languages including Maori, then maybe his or her good behavior and helpful participation in other Duolingo forums would be good evidence.
  • If he or she is seriously into Maori and likes several platforms including Duolingo, then maybe links to other forums about Maori where he or she shows good behavior and helpful participation would be good evidence.
August 23, 2015

I read somewhere that one of Duolingo's requirements for building a course is someone volunteering to moderate the course's forum. Is this true?

As far as a know, there isn't a place to volunteer specifically for this.

In the application form for the Incubator, you can choose whether you want to be a course moderator who carries more responsibility for the course (such as choosing the other contributors and making sure the course stays "on course" (sorry)). I think some of the course contributors (be they course moderators or not) then just somehow end up being forum moderators for the course specific forums as well, whereas other course contributors focus on other things.

August 23, 2015

Great job as usual!

August 24, 2015

Go Team Polish! Nice progress, keep it up!
