SNs and Libraries

Some people tend to think that social networking sites such as MySpace or FaceBook are not useful; there is nothing "educational" about SNS. However, if libraries (with their primary role as educators), get involved in SNs, it would be quite a different story. Libraries can glean through the profiles of its users and, based on what they see, they can select and disseminate educational materials that would help satisfy user needs.
Users may perceive the libraries using SNS as a part of their world, not as isolated repositories of knowledge.
