Anyone using Loopt

Loopt is a social networking site based on your location. You put in updates (like Facebook Status, or Twitter) and your location. It puts you on a map that only your friends can see. It also updates your Twitter and Facebook feeds, if you want.

I don't want to send out a blanket invite to everyone. That's annoying. So, if any of my friends are on
Loopt, let me know.
