Blogger sure picked a great time to give me permalink problems, when I've been getting cited by Ginger, Scott, O-Dub, Atrios, and Kevin. Republishing my archives seems to have fixed the problem, but I'm still leery. Anyway, thanks to everyone who's pointed people here. I hope the "page not found" errors hasn't discouraged too many of them.

UPDATE: Well, there's another possibility - I just got a message from Blogger that their server went boom, so no publishing is available. Sigh...
