i dont know if this is feasible, but i was wondering if their could be a way to incorporate "friends" on your profile page. i have built some good connections here over the years and providing an option to add friends and see when they are online or even make IM'ing available.
not sure if its possible, but the blog has evolved from simply posting about the celtics, to a community of celtics fans.
figured i would throw the idea out there.
