Hello,
we Russian-Language Support of Mathematica have some resources:
VK-community: http://vk.com/wolframmathematica
Habrahabr blog: http://habrahabr.ru/company/wolfram/
YouTube channel: http://www.youtube.com/user/WolframMathematicaRu
These resources are largest Wolfram communities in Russia and post-soviet countries.
Thanks for the suggestion, Roman! We'll take a look at these and get them up on the site as soon as possible.
