If you are really busy, skip my writing and read Robert McChesney's letter (seconded by Lawrence Lessig):

Ian Master's article in the LA Times is a chilling one for those concerned about free access to information on the web. Masters points out that the FCC "wants to give away what's left of the store to the broadband cable and satellite providers and make them gatekeepers or tollbooths on the information highway.... It used to be that the Internet was accessed via a common carrier, the phone company, but as technology has moved forward, these new unregulated media monopolies [i.e. cable and satellite companies] have increasing control over the information pipeline. Without regulation, they have the ability to choose what content they provide."

The shift from common carrier to unregulated carriers is really important, although at first the only apparent difference will be the speed of data flow. However, the real differences,and at first less obvious differences, are substantial. Not only will they be able to select content, they will commonly charge for content, and monitor your access, patterns of usage and connections with others (as ISPs can now do). The difference between then and now is that these new providers will be much more interested in mining the data for profit and to buy good will from a government bent on sweeping up vast amounts of personal information. Keep your eye on this development. You'll need to use all your alternative sources of information to monitor this because it certainly will never show up on FOX, MSNBC, the networks or print sources such as the Wall Street Journal.
