Discovered Stack Overflow Yet?

Software developers, programmers, and Informatiker (as they say in Germany): have you caught on to Stack Overflow, the forum for coding questions that is actually helpful?

By cleverly taking into account the sociological aspects of a discussion forum, the Stack Overflow team have created an excellent site. I find that when I post a programming question there, I get a sensible, working solution in less than 30 minutes. I've asked Java, XML, and Objective-C questions and have always received just the right answer.
