CBS goes Web 2.0

To promote top-rated CSI: Crime Scene Investigation for the month that Gil Grissom (William Peterson) is off doing a play in Chicago, the show is bringing in a mysterious cop character and to go along with the storyline CBS has put together a nice website called Who is Keppler? The site has user-contributed video mashups, tagging, rating, friend lists, Google Map of registered user locations and mobile content and is built with Palo Alto-based Ning.
