Wow thanks for still devoting your time to update us on the new courses


There's not much at all going on. For all the tweeks and a/b testing and endeavouring, It would appear that duolingo management regard course stagnation as, not even an issue. Clearly It is. There is a chance to spread courses that are rarely found elsewhere and make a huge impact, but at the snail's pace that is, there isn't much innovation. It's easy to criticise but the point is that there is potential for duolingo which is being missed as nothing happens. I hope that they can find a way to stimulate the scaling of the website/ app.


It seems that course stagnation is not even an issue. Clearly It is.

So is it not even an issue, or clearly it is?

ETA: The unmarked after-the-fact substantial editing of posts must be catching on in this thread. It makes for a meaningless conversation. I am out.


I'll clarify. It appears to me that duolingo is not interested in that glaring issue and is focusing their attention elsewhere and have no answer, or maybe motivation to establish or manage teams that show a slightly decent output. Some courses are moving at an average of 1% every few months, others not.


I can't wait to start learning Czech, thanks for all the hard work.


Thanks! Some waiting is still needed. Even if I punch the button on 7/7/17, we may need to allow time for the post-processing tasks by Duo that they could not do despite the advance notification.


Japanese has been released a few weeks ago (it slowed them down considerably) they will release Czech soon. Not bad IMHO.


I don't think they are that involved in other courses apart from Japanese, so one shouldn't slow down another. Also, after Czech and Italian, the next courses are below 60% and since courses seem to struggle to break 2% or even 1% per week, those two could well be the last new courses in beta this year.


Merci jrikhal! I must say Tamil alphabet looks very charming!


It's a descendant of the Grantha-style script of the Southern Brahmi scripts. These are abugidae (where the consonant marker holds the vowel instead of the vowel being represented with a separate letter). You should check out the other South-Indian scripts too!

  • Tamil: தமிழ்
  • Malayalam: മലയാളം
  • Kannada: ಕನ್ನಡ
  • Telugu: తెలుగు

Tulu has a Tigalari script, but nowadays it almost exlusively uses Kannada script, and I don't think there's Tigalari in Unicode yet, so...


I must admit, I can be quite lazy if left to my own devices, so I greatly appreciate the teaser you gave me! Oh the emotion involved in writing, for example, this இ! ("i"? "Yi"?)
Okay, clearly a noob question, but does the alphabet have to be in Unicode to, for example, be presented on Duolingo? I always thought the main block for Japanese was that there's no alphabet, but characters and a far more extensive combination level between them. Incubation process here is supposed to be automatic, but the system couldn't easily distinguish words. So, can you enlighten me here? Only if it doesn't take too much time; I don't want to obstruct course development, as an example!


Nobody has taken the time to make a typeface or a font for Tigalari yet, because hardly any Tuluva uses the script! (Tuluva = Tulu person). The script used today is almost exclusively the same script as Kannada (because Tulu Nadu is a part of Karnataka now and not its own state). Historically too, both have been very close, with the greatest Kannada emperor being from the Tuluvas.

இ = "I" (short, like in "win") [ ஈ = Ī (long, as in beat) , யி = Yi, which is the consonant ய + the vowel marker ]


Oh so it wasn't a question of formatting, but rather a "no typeface" problem. You've given me much to read, I might fall in love and learn the language, even. Thank you, for the info and for the explanation!


Thank you so much for all your work in doing this jrikhal! Though I think you may have forgotten to include the (A) and (S) next to the courses in the graphic...


Good catch LupoMikti!
Thx for the remark!


Yay! A million learners of Esperanto in Duolingo!


x 1,000 :-)

Edit: Oi, it's not that cool to edit your post significantly (and thus making responses to it meaningless) without acknowledging the edit...


How in the world do you have level 2 in hindi?


"a (past) bug/misclick by staff" is a definition of "magic" I didn't know. ;) ;)


Nah, a staff member inadvertently leaning on the switch that puts some content on this page, that would be some real magic... ;-)


That would be a common question posed to annika_a, I think :D


Indeed! My claim to fame...


And yet, still no one cares about this made-up language.


At least 1 million people care. 1,000,000 and 0 are not the same number. ;)


I would say starting a language (any language) and caring about it are two different things.


Congrats to the Indonesian team on the huge jump! (or is that a technical artifact of some sort?)


As the course's progress has drawn back 3 weeks ago, it's more likely due to addition/deletion of lexemes from the tree/template:

  • the draw back 3 weeks ago is probably due to addition of more skills/lessons/lexemes in the tree
  • this week jump is probably (partially) due to deletion of skills/lessons/lexemes from the tree

But, can't be sure.


Their overall word count seems to have stayed below 1300 during the new WIU era. Our hard minimum of 1500 should have stabilized the calculation so that only the completed word count would impact it.


@All, please forgot my previous comment. ;)
Thx nueby!

Hence it means that, 3 weeks ago,

  • either they deleted some sentences that were associated with some completed words
  • or they deleted some words that were considered as completed by the system,

and that this week they (re)completed many words.

In any case, the variations are good news (even the negative one): it means they're working on the tree. ;)


Doulingo's new course guide told me to contact you or Lrtward directly if I wanted a new language listed to the guide, so I guess that's what I'll do.

I was wondering if you could possibly consider adding Karelian. It's not listed on Doulingo's new course guide and has no post on Doulingo specifically for it that I know of. Which is why I made one myself here.

Thank you.


I really want to create a Serbian course for English speakers! I just applied for it in the incubator, I hope I'll be allowed to give this contribution :)
