Twitter/Facebook 23 Things

Cool stuff.  While I consider myself reasonably savvy with technology, this is one area (social networking) where I'm sorely behind the general populace.  I can't greatly imagine a scenerio where Twitter would prove beneficial in terms of reference work; yet, this could largely be due to the fact I've never used Twitter before now.  I can, however, easily imagine where Twitter or Facebook could be a great pubicity/networking tool for a library.  Also, I can imagine too that it would be a cool way to get instant feedback about potential library services and such by merely posting the question to your own followers.  As far as what's important to know for our patrons, it seems I get an occasional question about how to post pictures or how to "friend" someone, but these are mostly rare in comparison with other general computer, Office, or Web questions.  I've generally been one of the so called "haters" in regard to Facebook and other social networking.  Granted, this has not been a well thought out dislike; rather, it's often jokingly been one of "Do I really need to make that baby face kid any richer than he already is" type of thing :)  Having said this, I am starting to come around a bit in regard to it.
