Most of the sites which are popular so far are for nerds, because the nerds are coming from meta.stackoverflow.com. There isn't anyone else coming from anywhere else. I know there are lots of people who would post to a woodworking groupa woodworking group, but the intersection between nerds and wordworkers is small. Thus the woodworking proposal has only getsgot five votesfollowers so far. The whole business about saying "Oh you have to bemake a site for professional master woodworker"woodworkers", which is supposed to win everyone over probably will make no difference. Also non-nerds don't know the stackoverflow system of questions and answers with votes, so they won't see the point: they will just see it as yet another boring forum.
