Will Duolingo one day have more of the world's most spoken languages?

I'm wondering if one day Duolingo will add more of the world's most spoken languages? I know there are plans to add languages like Mandarin, Arabic, and Hindi, but what about the other most spoken languages:

Languages like:

  1. Bengali
  2. Punjabi
  3. Javanese
  4. Wu (Shanghainese)
  5. Telugu

And others as well. Do you think Duolingo will add these languages? Let me know what you think.

Also after reading more on, I see that it's unlikely Duolingo have plans to add more than one dialect per language, so it's unlikely Wu would be added, but is it likely different languages spoken, for example in India and Indonesia be added like Punjabi and Javanese?

That's a good question. I think now that they have created a better way to teach characters (Japanese Course) it is virtually certain that many more languages without the Latin Script will be added. I'm pretty sure this feature is being used for the upcoming Hindi course, so it is very logical it will be used for many more courses, including what you mentioned above.

And they are currently creating an Indonesian and Hindi, so I think it is very possible Javanese and more Indian languages will be added.

Oh, and yes, I think more Indian languages like Gujarati and Telugu should be added.

Is there a big interest in Shanghainese? I would imagine Americans would find Mandarin more useful, even if they work in Shanghai.

Courses are made by the community, not Duolongo themselves, so we just have to wait for people who speak thoses languages to sign up to contribute to the course, so the language can be put into development.

Yes, but as Duolingo grows, more and more people who speak these languages will be able to contribute.

The problem is, Duolingo decides whether the community can design the course. I've heard several Finnish natives have tried applying to contribute to the Finnish for English speakers course, but has not had any action on Duolingo's part. (i.e. it is still not in the incubator.)

Courses are made by teams of people selected from the community, but Duolingo decides which courses to create when.

As I understand it, many more people than needed have volunteered to be course contributors for most languages, so shortage of volunteers is not the problem. (In some cases, a shortage of volunteers who are truly bilingual in both languages and really up to committing to the hours per week involved might be.)

Duolingo likes to keep the number of courses in the incubator constant. Thus, it develops only so many courses at one time, regardless of other factors.

Duolingo is not particularly transparent about why it chooses some languages, and not (for the moment) others, but it appears to like a mixture of different types of languages.

They speak both English and Irish in Ireland, both Spanish and Guarani in Paraguay, etc. and Duolingo teaches Irish and Guarani too. ;)

I wish they would add many more languages! I was quite surprised that latin wasn't possible to do! There are many more languages not on this site and it would be so nice that every language of the world was possible here!

They will be added with time.
