It's a no brainer - the Monastery is simply the best programming-related community I know of on the web. The fact that its central language is Perl, which is one of my favorites, is almost irrelevant. Perl or not, the amount of general programming / software development wisdom one can accumulate here is priceless.
What more, the Monastery somehow manages to be more relaxed than the newsgroups. There's very little flame, and people talk more to the point.
