stackoverflow.com: With both Spolsky and Atwood involved, I suspect this will be huge.

Jeff Atwood and I decided to do something about it. We’re starting to build a programming Q&A site that’s free. Free to ask questions, free to answer questions, free to read, free to index, built with plain old HTML, no fake rot13 text on the home page, no scammy google-cloaking tactics, no salespeople, no JavaScript windows dropping down in front of the answer asking for $12.95 to go away. You can register if you want to collect karma and win valuable flair that will appear next to your name, but otherwise, it’s just free.

The no registration thing fits. Joel’s forums have been no-registration for years, and it’s worked out great — good content, good answers, very little cruft.
