The blogosphere sure is an interesting place. One of my blogging coworkers recently discussed the statistical significance of some poll numbers that a political blog posted to demonstrate that a certain Senate Minority Leader is in political trouble. My coworker is apolitical, from what I can gather, so he had no ax to grind. His discussion was more mathematic than political, and was sparked by a law professor's claim (on the professor's blog) that the poll numbers posted on the political blog were insignificant. The political blog is citing my coworker's discussion to make the point that the candidate's poll slippage may be significant. So it's a closed-end loop -- blog 2 questions blog 1, and in turn is questioned by blog 3, which is cited by blog 1 to support blog 1's original point.
