In a  previous post  I talked about  Stack Overflow , a site where developers can ask and answer development-related questions. It has finally gone live, and it's an awesome site. It's rapidly gained a high place on my list of development tools I can't live without.

Here's Joel's description of how it works:

Here’s how it’s supposed to work. This is a community project, so I’m being careful to avoid saying this is how it will work… that’s up to the community. But this is roughly what I have in mind.

Every question in Stack Overflow is like the Wikipedia article for some extremely narrow, specific programming question. How do I enlarge a fizzbar without overwriting the user’s snibbit? This question should only appear once in the site. Duplicates should be cleaned up quickly and redirected to the original question.

Some people propose answers. Others vote on those answers. If you see the right answer, vote it up. If an answer is obviously wrong (or inferior in some way), you vote it down. Very quickly, the best answers bubble to the top. The person who asked the question in the first place also has the ability to designate one answer as the “accepted” answer, but this isn’t required. The accepted answer floats above all the other answers.

If you're a developer, you need to use this site. Really
