Brightkite

Brightkite is a new social networking micro-blogging service that is based on geographic locations.

Users are able to update their location, see where their friends are and make new friends. The service can be updated via the Internet, text messaging, e-mail, WAP and the iPhone.

"I will never join BrightKite. Ever. It’s not for me. Believe it or not, I actually value aspects of my privacy. I’ll let you know where I am, but not through that kind of service. As far as you’re concerned: I’m at home in front of my computer."—Chris PirilloChris Pirillo: Dim Flight for Brightkite (June 14, 2008)
