Artist's communities

Today in Alyson's Art Biz Blog she talks about the need for artists to create and nurture community. Very timely post for me since I was talking yesterday about the importance to me of the critique group I belong to. So go take a look and also see her "Ten Ways to Nurture Your Community". I'm going to work on this. 

How would you nurture your artist's community or what sort of community would you like to have if you created one? 

Please post your ideas in the comments.
