Libraries and Web 2.0

I can definitely see some advantages for libraries with using social networking technologies. While some tools already in use, such as library blogs probably aren't seeing as much interaction as they could, others such as online video have much greater potential. case in point, the Youtube video UoN has created for Chinese speakers on how to use the Print/Copy system. Great idea, well exceuted, and definitely useful. I'm not sure I see the point of a Facebook page for the library, as what is popular moves on rather quickly (MySpace anyone?), but there is definitely a place for user-driven content.
