Will someone please explain Facebook to me? I've had multiple urgings from multiple sources to join Facebook lately, but I am in the dark on it. I have been inexplicably resistant to joining Facebook and/or MySpace, so I know nothing about that other than everyone seems to be on them but me. I have a family blog, so what is the point? Unlike blogs which omit personal details, the point is to provide personal details, yes? How does the whole social networking thing happen? Does everyone use their first and last names? If married women, do they provide maiden names so old high school friends can find them? How does this work? What are your user tips? Would you recommend it? Please explain it to me like I'm a know-nothing, behind-the-times out-of-touch person because well, I am a know-nothing, behind-the-times, out-of-touch person when it comes to these things.
