(If you're reading this in Radio's News Aggravator, it's probably not unencoded properly. Don't blame me!)

(If you're curious about the answer, it's probably better to email me than Hixie. That way he won't get spammed by the propagation of the link. I'll only respond to honest guesses, though.)
One day, I'll fix the HTML on this site. Honest, gov.
