Tribe Founders Launch Startup Aggregate Knowledge

Paul Martino and Chris Law, both founders of Tribe Networks, have been hanging out at the NSV offices and working really hard on their new startup, Aggregate Knowledge. They have a recommendations web service, WSRelater, live now on the web. I've played with it, and it's awesome. There is some impressive math behind the engine, and the number of cool things I can think of to do with it is rather long. Keep them on your radar screen.
