Jay Rosen has a very good post about how the Downing Street Memo has finally made itself known in the traditional press and what this says about traditional notions of news judgement (The Downing Street Memo and the Court of Appeal in News Judgment). The very interesting conclusion:

I don't think the press has learned how to deal yet with "power shapes truth," or the extreme contempt for reason-giving the Bush Administration has shown on matters of war and peace. For example, in judging whether a story deserves further play the press will ask, "were the facts in it previously reported?" (a news test) rather than asking: having the facts in it been successfully denied at the top? (which is a power-shapes-truth question.) Ultimately this confusion helps explain the original judgment that the Memo was not news, and the success of the appeal. [emphasis, links in original]
