friend networks...kind of interesting but not my style

I think that this is the future of social interaction for a lot of youth, but it's not my style. It is very worthwhile to know more about how these sites work, though since we handle a lot of patron questions from people using pc's. I don't care for the way the sites are set up, but it's cool to connect with people you haven't seen since your school years. I don't really see an application in the library system for this however.
