Popular science in the blogosphere

There are more than 46 million blogs on the Internet, and his is the most read science blog. Pharyngula, by PZ Myers, is the world's 179th most read blog on any topic.

Myers is a biologist and professor at the University of Minnesota, Morris. The sub-head on his blog provocatively reads: "Evolution, development, and random biological ejaculations from a godless liberal."

Myers' writing ranges from explanations of scientific concepts to tart critical ripostes about right-wing politics. He talked with MPR's Tom Crann.
