I went to the Web Innovators meeting in Boston last night (April 2nd, 2008). I made these recordings after looking at a number of the demonstrations. I'd originally planned on writing them up, but given time constraints, I'm going to leave it with the original audio. Sorry About the quality, it was a *very* crowded ballroom.

While they are currently a shopping comparison site, I think if they have something real (they invoked the magic phrase "Artificial Intelligence", which generally means, "It's kind of fuzzy, and we aren't going to tell you the details") they will eventually end up licensing it to other companies rather than competing directly themselves.
