I’ve just installed WordPress plugin which allows use of category specific RSS feeds on this blog (this one). It means that if you interested in some new posts which appear here, but only on specific topic you may use category specific RSS feed as opposed to general feed which contains all sorts of posts on various topics. For example you may want use K2 or Tech or Language Learning category feeds if you interested in some specific topics only (which most likely in the case). I also placed K2 category RSS feed link on a side bar for convenience.
