Have just finished the book and was both enlightened and a little surprised by the content of the book. The argument for the perversion of the media by the "grocers" was one I was unfamiliar with, but which makes perfect sense.
I read your book alongside Dr Ben Goldacre's 'Bad Science' and am consequently thoroughly disillusioned with the media and disheartened as to our future as news consumers.
The relative empowerment of the individual voice arising from the proliferation of the 'blog' is more than neutralised by the mass media's acceptance of V.I. Lenin's assertion that "a lie told often enough becomes the truth."
The only solution I can suggest is to string 'em up, as it's the only language they understand.
