I heard Andrew Keen promoting his book The Cult of the Amateur: How today's internet is killing our culture on the radio, wherein he decries the celebration of the anonymous, unedited, citizen hacks, high on cheap kit and broadband, who are devaluing the media. He then rather brilliantly disproves his own point in his blog AfterTV, as he manages to bring some interesting and diverse opinions on the media to light, via his own amateur business TV news service.
