Social networking

I'm suspicious of the whole social networking thing. First off, I'm not very sociable. Secondly, I'm pretty private, I don't want to tell the whole world about my every action. Thirdly, and perhaps most importantly, I don't really need another time suck, I'm a blogger. Still I'm told there are some practical uses for it--publishers like prospective authors who can contribute to the marketing of their books--so I'm giving it a shot. I just set up a Facebook page. If I'm feeling especially bold, I might even try Twitter later this week.
