Twitter

Twitter is actually a fairly interesting site where you can find out pretty much everything that's going on in someone's life, in the world, etc. in a matter of seconds. The main use of this type of site for library purposes would be a kind of answer and question sort of thing where people can get a quick answer by phone, e-mail, or web browser.

Just in case you're interested, and I just know you are, my twitter user name is: Maverick4527
