I've been trying out this new social networking site called BikeSpace this week. The creator posted about it on the Craigslist bike forum asking for beta testers and it is currently in open beta. Not too many users yet but the site definitely has promise. You can map your favorite routes, show off your whip, organize rides, and I think some other stuff. There's still a few quirks in the coding (particularly when using the Safari browser, which is a pain) but it's pretty nice for a beta. Any other BF members using it?
