One thing the article didn't discuss in detail: Without a doubt, English is used by non-native-speakers around the globe as a lingua franca, and this helps explain why more than half of all websites are in English.

On the other hand, I would assume that German (now in third place) is used primarily by native German-speakers, and that native speakers of Dutch and Swedish and Czech (for example) are more likely to prefer English as their lingua franca instead of German.

So I'm curious about the percentage of users on the Russian-language internet who are using Russian as a second language or lingua franca, even though Russian is not their native language. (I'm not counting people like myself who can speak Russian with "clumsy fluency" as a foreign language -- I'm only talking about people who regularly use Russian as an acquired second language.)

I mean to say, how many Uzbek and Kazakh users would prefer to read websites in Uzbek or Kazakh if such sites were widely available -- and how many would prefer to read websites in Russian because they don't speak/read Uzbek or Kazakh sufficiently well?
