Chris Bowers has two really interesting articles via MyDD on the right/left blogosphere. Here's his first article on the topic. Follow that up with his second post that has a response from Patrick Ruffini: Yet More on the Two Spheres
As always Chris crunches the numbers and it's not the "we're better than you because.." type of research. He lets the figures do the talking. Plus it was nice of him to include C&L as a "New Rising Star"
I'll write more about Ruffini's rebuttal of "we link more than you do" argument a little later.
