library 2.0

I like the possibilities offered for social networking in Library 2.0. While I personally may not want to use these on a regular basis, I'm aware as a mom and as a librarian that libraries must evolve in the web 2.0 environment in order to be current and stay user-friendly and relevant for young adults (not as in YA, rather as in people in thier 20's, early 30's) and younger. The one concern I have has to do with issues of privacy, something I didn't see any of the perspectives I read comment on. Progress continues to progress.
