If you have not seen StackOverflow, I encourage you to get familiar with it right away. It is a great resource for software developers among us. The site went in public beta two weeks ago and it is basically an hybrid between a wiki, a blog, digg, and a forum specifically dedicated to answer programming questions.
It is self-moderated and it works. Questions are answered in a matter of minutes and noise is quickly eliminated. It is fun to try to answer questions and it is certainly an humbling experience as many out there are much more savvy than I am.
