I'm sure you all are aware of Stack Overflow, the question and answer collaboration site for programmers. Joel Spolsky is one of the people involved with the site. Anyway, I think the site has just hit a critical mass state because it's been appearing more and more on my programming research Google queries. I noticed it a couple of weeks ago and have had several more hits this week. Maybe it's just a coincidence or maybe its a good time to check it out again.
Has anyone else been seeing it more in their query results?
