Burning question in the Blogosphere

In case anyone hasn't seen it, there is some controversy out among various more politically-oriented bloggers regarding an aspect of Jared Diamond's latest book, Collapse: How Societies Choose to Fail or Succeed. The whole thing was started by a guest blogger at Andrew Sullivan's blog. Basically, it was a comment on the political tone of Malcolm Gladwell's review of the book, but has since snowballed somewhat into a discussion of Greenland Norse dietary practices.


Matthew Yglesias posted thrice on the subject (here, here, and here) and also someone named Fritz Schrank.

We are noncommital at this point, but the issue probably needs some work, if any interested readers out there have anything to say. We found a couple of papers, none really referencing fish consumption, but at least one mentioning extensive use of other marine life (seals).
