OK, this time I really mean it. Honest. I am done with the Panda's Thumb. First of all, they don't post as often as they used to. Secondly, their posts are not as interesting. Thirdly, their commenters are (for the most part) the same people saying they same things yesterday, today, and presumably tomorrow. And finally, I think their site is hosted on a Commodore 64 in PZ's garage. It can takes ages to download their main page, if it downloads at all. I'll go there if I am directed from another post, but I'm through browsing PT. It's a site that's so 2005.
For "opposition" sites, I’d recommend both Jason Rosenhouse's Evolution Blog and Ed Brayton's Dispatches from the Culture Wars.
