How to filter posts on planet.fedoraproject.org?

[Pavel Alexeev (aka Pahan-Hubbitus)]

Hello.

I'm open for himself planet.fedorapeople.org not so long before. Even 
try add there my own blog.
But I'm wondering how I can filter records which I read via RSS by 
language!?
I want read only English and Russian blog posts. Unfortunately I do not 
known other languages. But quite half of messages come on Indian, 
Arabian, Spanish and etc. I always just delete it. But it is serious noise.
