Everyone should download and listen to the Optimize magazine's podcast interview with the author of Wikinomics, Don Tapscott. This new business book, Wikinomics, explains how "smart companies" are using the value of Web 2.0, and social networking software to increase online design collaboration, and thus increase the speed of VPD (velocity product development).
