Academia.edu - social networking for researchers

Academia.edu is a new social networking site created by some researchers from Stanford and Oxford. It's worth a visit if you are a researcher interested in making connections with colleagues across the world. Visitors to the site can add their own profiles and the profiles are connected to each other by a user friendly tree diagram. Over 14.000 researchers have already created a profile, some noteable examples: Richard Dawkins, Stephen Hawking and Noam Chomsky.
