Fox Business had me on this morning to introduce its viewers to social networking. I explained a little about what it is, who the big players are, and why it's popular. I talked about the differences between the three big companies, MySpace, Facebook, and Bebo, and why people like them. We're a social species (I said), and socnets replace the kind of face-to-face casual conversation we'd have if we all lived in the same small town and ran into each other on the streets every day.
