The Symbiosis of Blogs and the MSM

THE SYMBIOSIS OF BLOGS AND THE MSM….Steve Benen suggests that the blogosphere is getting more respect from the MSM these days:

FireDogLake’s coverage of the Libby trial was must-read content for reporters covering the case. TPM has [made] the purge scandal what it is today. It’s getting increasingly difficult to dismiss the blogosphere’s “dirty hippies” as wrong and irrelevant.

It’s an interesting dynamic. In both of these cases (Plamegate and Purgegate), it was the MSM that did most of the primary reporting but the blogosphere that showed the better news judgment. Why?
