Scienceblogs torpedoes its own credibility

UPDATE: The management has acceded to the demands of the Scienceblogs posters and agreed to dump Pepsico.

I like Scienceblogs, a network of blogs about science, written by scientists. I've mentioned PZ's blog, Phrayngula, here more than once, and I'm also a fan of Dr. Isis and some of the others.

So why would they do this? Why would they give space to Pepsico?

PZ and Romenesko have the story.
