My friend Rob just recently checked out a website that calculates one's contributions to the open source development scene. Apparently it's also got some social networking stuff in it, although I never saw anything of the sort. Anyway, the site is called Ohloh.net, and it gave Rob this nice little badge (below the fold):

Rob is quite impressed with the service, but I don't think that the service would be quite impressed with me. As far as I can tell it won't count code check-ins made by others on my behalf, which pretty much means it won't count my old Mozilla contributions... :(
