The last thing media companies want to become is irrelevant. This can result in "tech trend" reporting that verges on the overzealous and absurd. Lampooning this tendency, Comedy Central's Jon Stewart observes the media's coverage of Chatroulette, a video chat Web site. As he takes a spin around the Web, he encounters a who's-who of bashful TV commentators and personalities. Kudos to Keith Olbermann, Katie Couric, and Brian Williams for genuinely humorous cameos:
