Discovr aims to change all that.
Discovr allows people to disclose their location online, or via their phone. Through the friend networks already established on LiveJournal, Myspace, Facebook, Friendstr, etc, Discovr lets friends find each other in the world.
What is really nice is that you don't have to do anything special, you can login directly with your LiveJournal account. No registration forms to fill out!
... how is the relevant to UW... well, it was made by soon-to-be UW graduates.
