First, where’s Pharyngula? Like him or hate him P. Z. Myers has to be high on this list. Where’s Cosmic Variance? Not Exactly Rocket Science? Perhaps some of these weblogs opted out of the rankings, I don’t know. But whatever is going on, something doesn’t pass the smell test here. For what it’s worth, my own weblog is ranked highly, but at the old URL, so I assume I’ll slowly start journeying south on the rankings as people start switching links.
