Gerry Mckiernan, Science and Technology Librarian at Iowa State University Library, posted the following to lita-l@ala1.ala.org and several other lists of interest to librarians.

I’m pleased to announce the launch of Friends: Social Networking Sites for Engaged Library Services, ‘a blog devoted to application and use of online social networking sites such as Facebook and MySpace for any and all types of library-related programs or services.’

Friends will include announcements, general news, as well as citations and links to significant articles, books, and other publications about online social networking in general and their use by libraries and librarians.

The Friends blog is at: onlinesocialnetworks.blogspot.com/

Their FeedBurner feed is:
