Recently StackOverflow started a Russian version of the site because of the huge contribution of the Russians to the IT and English StackOverflow.
My question is:
If the SE management team decide to start Math.Stackexchange in a new language, what should that language be? How to choose it? What are the important parameters for choosing it?
I think possibly the number of original site users who speak a special language as natives is the key parameter here. As I found many Chinese people here, possibly Chinese language could be an option but I have no idea what the real status of native speakers of different countries is in Math.Stackexchange.
Another parameter could be the popularity of the site among different countries in the sense that the countries with large enough population that Math.Stackexchange is more popular in them with respect to the others, are more rightful to have a version of Math.Stackexchange in their own native language. Again, I have no idea about the statistical situation of the popularity of the site in different countries.
Any reference to related statistics could be also very helpful.
