Poll: how do you use social networking?
I don't personally use social networking. Call me a Luddite, but I value personal interaction. Its not clear to me if others use them liberally, occasionally or not at all.
Real world social networking, aka going out to network events and breakfasts, meeting people, sharing information about third party products and services I like through word of mouth and keeping a network of RL people ... can't get enough of that.
