My post about the Post editorial got screwed up, so that it merged with the next post down and I couldn't get to the edit link to fix it. I got all worked up, and wound up viewing source on the lower Blogger window, stealing the address of that edit link, and typing it directly into the address bar. Then Amanda pointed out the "enter safe mode" link, whose alt tag says "If you accidentally type some bad HTML that renders the edit link for that post unreachable, click here." D'oh.
