Google sent Tom Leung to System 2008 to explain their Web Optimizer program.
On this video we hear comments on Tom's talk from Perry Marshall, Glen Livingston and Howie Jacobson, three of the sharpest Google AdWords people on earth.
Then we eavesdrop as Tom shares some fine points with attendees after his talk.
At the end of the clip, you can see the beginning of Tom's talk.
Needless to say this presentation straight from Google headquarters was one of the highlights of today's conference.
