iLibrarian on Facebook use and apps

As I'm preparing for my presentation tomorrow by reading through my assigned blogs (I have about a million entries saved in my Google Reader!), I found a few entries on iLibrarian about the best Facebook apps for librarians and the hottest Facebook groups for librarians. This, I think, adds to the case for keeping the individual page for the branch-- so that these apps and groups can come into play, making the library a more "active" participant in Facebook. What do you guys think?
