Blogs seen as powerful new tool in U.S. court fight

Yahoo is carrying the following Reuters’ article: Blogs seen as powerful new tool in U.S. court fight which talks about the role that blogs could play in the upcoming Supreme Court nominations. Pretty standard stuff, but I thought the following paragraph was interesting:

Not all blogs are created equal. Many will become “ideological echo chambers” that people read to reaffirm their beliefs, Clemons said. Others will fuel passions on both the right and the left sides of the political spectrum. A few will rise above the pack and become sources of information and not just an advocacy forum.

What I would like to know is which of the traditional, brick and mortar media outlets rise to this high standard?
