I'm not really interested in this right-left discussion. To me its a power-grassroots discussion. Disenfranchisement comes in many forms. To me blogs represent a nonpartisan method of the grassroots being able to hold those in power to speak the truth and to be deeply transparent. That is a fundamental shift.

If you fail to understand why the vast majority of blogs, and the accompanying success of the blogsphere, came into being then you'll never understand why liberal media will fight the blog movement, even when they harm their liberal friends like DailyKos or TalkingPointsMemo. The blogosphere is all about politics, no one can claim to be a fence-sitter. In fact, most blogs to the left and to the right enjoy vivid exchange with other blogs on matters of politics.

Believe me, you can't talk away liberal bias in old media by ignoring it, and you can't cure it by ignoring it. The benefit of the 'sphere is that it makes visible bias on both sides, and that both sides still have the feeling that they get their fair share of public representation.
