Political Blog Polarization

Political blogs are highly polarized into liberal and conservative camps, with little subgrouping within each camp and little linking between camps.

[A] set of 1225 conservative and liberal political blogs [was sorted] based on the network of web links between them. When the network was fed through the algorithm, it divided cleanly into conservative and liberal camps. One community had 97 percent conservative blogs, and the other had 93 percent liberal blogs, indicating that conservative and liberal blogs rarely link to one another. In a further twist, the computer analysis was unable to find any subdivision at all within the liberal and conservative blog communities.

Hat Tip to Coyote Gulch.
