I sometimes contribute to Wikipedia to various articles. I only contribute to articles where I am sure I have enough knowledge :).
I don't have time to contribute as much as I'd like. Sadly, there are too many badly written articles (yeah, speaking of those biased articles, in the romanian wikipedia).
My site is: http://www.robodesign.ro
Have fun and don't vandalise articles on Wikipedia. Also, don't try to make your biased point directly in an article (there's a discussion link).
