Russian quizzes getting popular

I've noticed that Russian quizzes are getting popular. When I've started making these quizzes we've had just a page of quizzes (around like 30-40 quizzes).

Now, we got six pages of Russian quizzes. Obviously, not only users from Russia access them but also folk from post-Soviet countries and areas with significant Russian-speaking diaspora like Berlin, London, Belgrade and so on.
