Stackoverflow gone public! This is a site for programmers that works like a wiki with a unique approach where anyone can ask/edit questions and collaborate on finding answers to those problems. The site defines itself as:
Stack Overflow is a collaboratively edited question and answer site for programmers — regardless of platform or language. Jump in and share your software engineering expertise! No registration or account required.
I find the view of the site about finding answers to technical questions interesting. Be sure to check it out.
