I really don't know why people do things like facebook. Call me old school, but IMO It's idiotic to post ANY information about yourself unless you absolutely have to. Say if your making a purchase at amazon or something. Not much choice then, billing info being what it is.
But social networking sites? Hell, even messageboards. I wouldn't even so much as give out my first name. People i've talked to/worked with here over the last few years don't even know it. So posting all this info about yourself on facebook, In my mind, is absolutely insane.
Now about the bit on camera's. I have to wonder if i really am caught on camera 200 times a day. Being caged in this cubical.... i kinda doubt that.
