From our discussion yesterday on blogs and bias: I think there's an incorrect comparison being made here - like writing off all print media because of Bat Boy on the cover of the Inquirer. The blogs I read tend to have a liberal viewpoint, and that influences some choices in which stories they cover. But, on the whole, the coverage of the issues is fair, balanced, and (mostly) free of vitriol.
It's a mistake to tar these decent blogs with the same brush used to paint those "other" blogs that use vitriol and falsehoods to push an ideological agenda. That's a whole different story.
One example of a fine blog: Talking Points Memo. War profiteer pays Republican senator $700K in exchange for defense contracts. U.S. media yawns and goes back to covering the Michael Jackson trial.
