[http://c2.com/cgi/wiki Ward Cunningham's C2 wiki] a.k.a. the Portland Pattern Repository. This is where the wiki concept was born. Unfortunately, it seems to have become inhabited by people who have a lot of time on their hands (and therefore can overwhelm other users), but are more interested in wikis and philosophy than in writing articles about software development. Flamewars and misinformation abound, and make the useful content hard to find.
