Query: Excellent map of the new media landscape

This is a superb documentation of how people want to use and are in fact using the new digital media technology.I'd strongly recommend it to anyone who is trying to make sense of what's happening in the media industry and society at large. Big changes are afoot and Lasica does a suberb job of mapping the new landscape and anticipating where things are headed.
