A couplf of weeks back, I assembled a Scorecard of Online Political Writers. I didn't see the need to try and limit to blogs. I wanted to research how various online writers, whether they identify as bloggers or not, exhibit aspects which are associated with blogs, as well as the civ structure. Included are Timothy Noah, Joe Conason, The Note.
My main aim was for diversity of structure; I couldn't hope to rank by a quality metric. I also included Malkin. I did so because of her high ranking in the TLB ecosystem. Also she added some diversity to the mostly all-male review (the group near-blog The Gadflyer has a principal columnist in Laura Rozen.) Savor the irony-- Malkin the beneficiary of affirmative action.
Ultimately, I would like to see a "Top 25" (here, there or anywhere) based on standard journalistic metrics-- e.g., whether, the stories are original research, whether the production as a whole is cohesive, and thus, whether it is valuable to read.
My comments on the PDF list: Winer's angle is not fresh but quite stale. And MyDD is vastly underrated. Not only are Armstrong & Bowers Kos's "blogfather", but in areas like the DNC Chair race, they've provide much of the primary sources which Kos references. And Marshall's abscence from Technorati's top 100 is striking. He is regularly in the top 10 of TLB ecosystem.

Why in the name of sanity have you included Michelle Malkin?
Have you read what that woman has to say about the Japanese internment camps? Why Micah, WHY?!?!?!?!
