I signed up on O'Reilly Connection; Chris brought it up. I think I signed up for a couple other of these social doo-das, but strictly as a leaf. Somehow this seems more useful; maybe because it's more targetted.

Anyway, I added a couple connections when I signed up, but probably missed many people who were already in there; if you (yes, you personally, I'm customizing this feed just for you and no one else is seeing this, I swear) sign up, you can connect to me too.
