Forbes Publisher and Innovation Editor Rich Karlgaard recently sat down with Prabhakar Raghavan, Andrei Broder and Justin Rao to talk about predicting user behavior online and the future of Web experiences. In the first interview, Karlgaard poses the question "Why is science suddenly so important in predicting consumer behavior on the Internet?" Yahoo's data is eliminating the need to speculate or rely on intuition. See the video here.
