I notice many people want languages on Duolingo like Finnish (which I want just as much), but I notice that many people don't talk about the Balkan countries' languages.
I've seen some comments about people who say they speak Croatian, Albanian, and Bulgarian, and would love to be able to make them courses on Duolingo. If I were to choose a Balkan language to put first on Duolingo, it would be Croatian. Serbian, Bosnian, Albanian, Macedonian, Montenegrin, and Bulgarian are runner-ups, in that order.
Croatia is a touristy spot, and to learn it from English would help many tourists. Croatian isn't a bad idea to start with the Balkans, too, as it is spoken widely, and is very close to Serbian and Bosnian. It does have two dialects, though, Chakavian and Kajkavian. I would love to see this language appear on Duolingo, as it may be the start of language courses popping up one after another.
As an unrelated side question for the Arabic teachers and coursemakers, will there be a Lebanese and Syrian Arabic course afterward if anyone knows those dialects?
I'm not an Arabic course creator or an Arabic teacher, but I do know that Duo has no plans to add other kinds of Arabic for now. So right now we'll only get MSA.
