Social networks

What a coincident, 2 weeks ago, someone told me about Facebook, you can find friends and share photos with your friends, here I am in week 12 of learning 2.0 program about social networking by using Facebook
and MySpace.
The video introduction of social networking is so amazing show that how people interact, you get to know your friends' friends and so on, an extend connection.
Social networking will be useful for client interaction in the library, they can leave comments, discuss their favourite books with others users or library staff, for marketing the page can be useful to display Local History photos for users to view. To promote library services, collections, school holiday activities, any events like internet classes, HSC exam preparing sessions etc. Librarians can invite users to participate a quizz competition. As well as interact with library staff, they can tell us what they like and don't like about our service, in that way we can keep improving and provide a better service.
