I realize the potential Facebook has with it's member base, given the inherent nature of Metcalfe's Law but I use Facebook to keep in touch with my friends who aren't savvy or willing enough to use Twitter; a networking site that doesn't expect it's users to sit by idly while companies poll and query us to sell products otherwise we wouldn't even blink at.
