Please bear with us as we work on some technical issues here, which have driven us to the use of this bland, neutral site template.
Update, 1620 CDT: A-ha. Apparently leading an entry with the term “CC” gets the post-slug written in such a way that it triggers mod_security rules. Such a pain. We’re back to the old style now. Sorry for any confusion.
I was just about to comment that the problem seemed to be isolated to that one post, but I guess you beat me to it. :)
