(Responding to this.)
You need to check your definitions. Citizen journalism could conceivably lead to mob rule or could be exploited by fascism, but the real danger of fascism is in the corporate-compromised so-called mainstream media. This is the media that beat the drums for war in Iraq (including the Washington Post and the New York Times, mind you). This is the media that still, after the Democrats have won Congress, overrepresents Republican and conservative points of view, especially on television. This is the media that until very recently rolled over and asked the Bush White House to scratch its belly in exchange for childishly credulous access to the latest Rovian spin - and was willing to type up that spin as if it were true even when the reporter *knew* it was a lie. This is the media that stridently dumps on the earth tones and the haircuts of prominent Democrats, while fawning over Duhbya playing dress-up as a fighter pilot, a rancher, or even a man in control.
So, while I still read widely in the daily press, no one who wants to be informed can omit the citizen journalism of the Internet, particularly the blogs. The virtue of the Internet, at least, is that there is more than one mob. The mainstream media practices much more "journamalism" than real journalism anyway. When the mob comes, if it does, the mainstream media won't protect us from fascism.
