For some reason the individual archive page for my last post and the January 2007 archive aren't accessible. That means no one can read more than the first two paragraphs of my last post (unless you read it in an RSS reader, which for some reason is working fine), and no one can comment on it. I'm guessing the same will be true of this post. I'm not sure what's going on at this point, but I'll let you know when things have been resolved.
Update: Interestingly, posting a new post seems to have solved the problem when a complete site rebuild did not. I don't know what the issue is, but I guess it's now resolved.
Update 2: Or maybe Matthew fixed it while I was writing the second post. It turns out he was making some changes at the same time.
