Social Networking - Italy

I had a look at the Library Beebo but couldn't work out how to add a comment. I wondered if you needed an account before you could do this. I have a Facebook account but not a Beebo one.
I found an article "Stalking the Wild Appeal Factor: Readers' Advisory and Social Networking Sites" in Academic Research Library. It was talking about using sites like LibraryThing, Shelfari and GoodRead to help in Readers' Advisory work. I love LibraryThing but hadn't really thought of it as a social networking site. I guess it is if you get into the discussion boards and 'follow' people with interesting libraries but I don't use it like that. I do check my Facebook page every day. Quite a few of my in-laws are on Facebook and it is a good way to keep up-to-date with their comings and goings. David's sister and her husband have recently moved to the UK and I enjoy reading their updates as they find jobs and places to live. I don't bother with the quizzes (particularly after reading Philip's email) but do play some of the games.
