I have had a chance to see some library social networking sites.  They look like a good way to share ideas and communicate library news.  I see how nice it is to have the pictures to go along with the posts, too.  Some of the information I found I might not have found too easily otherwise.  I thought about how social networks could be used for library programs to spark interest in middle and high school students.  It also could give parents an example of a positive way to use social networks.
