What I find funny is how in the beginning Jeff Atwood resisted all of these "social" features like discussion sites and official chat channels because it was all about asking and answering questions. And he wanted to build a community around that. What he didn't realize is that a community is defined by those "social" features. Experts Exchange doesn't have a community because they don't foster the social aspect of the experience.

At least Jeff realizes that to build a community, you need to let the community engage itself and has eased up on his "no social features" stance.
