Having listened to the audiobook version of "Tuned In" by Craig Stull, Phil Myers and David Meerman Scott, we thought we could make an episode out of one example. Zip Car was mentioned as a Tuned In product. We have never heard of the concept so everyone was given a task to find out more and discussed. In short, this is a community car concept, which is somewhat different from traditional car rental service. For more information, you can visit the http://www.zipcar.com site, and link such as http://www.youtube.com/watch?v=Uux8uSRDFK0, can provide a visual explanation.
