Social networking sites

My twenty-something offspring uses the sites as an absolutely vital and integral part of his social life. However, I guess I am just not excited about social networking sites. I do not understand who has time to post and who has time to read about the minutiae in other people's lives. I worry about privacy issues. As one who has shared personal genealogy information with trusted contacts, only to find out that a third or fourth party has posted the information on my living individuals elsewhere on the Internet is frustrating and disconcerting. I am sure social networking will evolve and become the new social order even before my generation is gone. As far as MySpace goes, the sites I visited were in a cookie cutter format and not entirely readable due to font color choices. Facebook has a cleaner interface and display. My library has a very complete and informative website, but I do see the need for integrating it with patrons and social networks. Seeing the practical application and efficacy will take some time for me.
