Are blogs having an effect on the UK MSM?

In a post on Ian Duncan-Smith's piece on blogs, Melanie Philips points out that it being published in the Guardian may be significant.

[The] Guardian's editor, Alan Rusbridger, is astute enough to grasp the nature of the gathering threat to the MSM. Word has it that he intends to use the opportunity afforded by the imminent radical redesign of the Guardian into a format somewhere between a tabloid and broadsheet in size to 'put the "r" back into reporting' -- in other words, to rid its news pages of their fabled prejudice and bias.

It would be nice to think that this was down to UK blogs, but it's more likely that he has seen the way the tide has turned in the US and is trying to get ahead of the game.
