I've participated in many SE websites, I get the point that it isn't supposed to be like yahoo answers, where people who know little are answered by people who know less.
From comments, I'd get the impression that this is not a website for learners but instead for fluent speakers who who are asking highly technical style and usage questions, similar to the English site. This is at odds with the fact that many questions are posted in English as if the questioner isn't even good enough to write his question in Russian.
If it is site by and for experts alone, that's fine-- no one would confuse me for a fluent speaker, least of all myself and I could avoid a good deal of unnecessary abuse by watching the expert ask each other questions instead of myself getting involved and asking questions. Maybe the FAQ could make this more clear about the expected fluency required to ask a question without getting pounced on for not doing the preliminaries (like, well, what are the preliminaries for speaking Russian? Growing up with Russian parents? Getting the PhD in Slavic studies?)
