We know Jeff and Joel use Stack Overflow (obviously), but what other "famous" developers or at least working on popular projects, or important blogs do you know of that are using Stack Overflow?
Book authors, popular project leaders/developers (think VCS, an IDE, a database engine, etc., stuff we ask about here at Stack Overflow). I mean famous as in "has done something important for the rest of us".
I've written books about programming, but I'm not famous. 99% of the people mentioned in the answers here aren't famous either. John Resig, Miguel de Icaza, and Ray Ozzie qualify as famous. The other dudes, meh.
