Social Networking and Libraries

In general I support having a library presence on MySpace and Facebook, although I don't know how much we're really drawing folks in. I haven't seen more kids come to programs because we posted a bulletin about it. Most of the comments we get on our YAAB MySpace are from authors. The polls we place online are often only answered by the kids who actively participate in our YAAB anyway. In short, I'm not convinced that we're staying hip with the kids.
I think we may need to mix things up. The idea of a catalog search function on our MySpace might get kids more interested in and comfortable with our webpage. Maybe try having staff available for MySpace IM'ing a couple hours a day for homework help. Maybe getting kids who participate in book groups to write reviews to post in a blog. A poll asking what kids have been reading, or the worst book they ever read? Actively 'friending' teens in our area? I don't know.
I agree with the Other Librarian that there may need to be a shift in thinking to make these sites really useful and engaging for library purposes. And I'm not even sure any of my ideas are quite outside the box enough. It just doesn't feel like we're using this technology to the fullest. Yet.
