I think it goes even deeper than the matter of competing news interests. We're a threat to their power to control the flow of information. In the old days, the Swift Boat story would have not made an impact. In the old days, the AP could have lied about the booing at Bush's speech and there would have been no way to counter that story in realtime. Now, every time the media either lies directly or lies through omission, there are hundreds if not thousands of folks ready to jump on every single error. Their power to be kingmakers is slipping through their fingers, and they will become more and more vicious as their power wanes - which, ironically, will only hasten their demise.
I agree. Well said. This article itself is an example of their frustrated, impotent bitterness.
