silverfox1 saidTwitter I use for fun....following celebrities, making comments to them (and them not answering).
Facebook I use for business.
Heh, mine's just the opposite. I tweet links to interesting articles about programming / info security, and help advertise some of the client sites I work on. On Facebook, I go under a false name and use it to plan camping trips / events and whatnot. I don't follow many people on Twitter; only other programmers, hackers, and bloggers that I find interesting and want to keep up with.
