This will be interesting to follow, possibly entertaining, and perhaps productive in the long run. Michael Arrington's TechCrunch has had some problems with Comcast of late, and although nothing has appeared on TechCrunch yet, Arrington's venom is spewing out on Twitter. Apparently someone from Comcast told Arrington that it is a state-wide issue in California, and of course that got debunked pretty quickly. Jeff Jarvis links to a TweetScan search of how it is spreading and says Arrington is one person you don't want to piss off.
Maybe it will take a big gun like Arrington to catch Comcast's attention. I know I've certainly tried, as has good friend, Ink Blogger Mark Sumocat Sumimoto. Rock 'em, sock 'em.
