A librarian's social networking site

Unsure about if or why you'd want a MySpace account? What if it was a social networking site for librarians? There is just such a thing, called Library 2.0 that I found, through my Bloglines account, from Jenny Levine's The Shifted Librarian. Bill Drew started this site a couple of months ago and it's growing rapidly. So, if the idea of being able to network with other social librarians is up your alley, check it out. http://library20.ning.com/
