It's the funky apostrophe in Pillar's name. Reply to yourself.. remove her name, the apostrophe, and the quote tags.. save.. and then I bet you'll be able to edit.

This isn't a good thing, but at least I know where to start tracking down the problem. I was having the same problem with the apostrophe in Mitt Romney's name from the WashPo article.. Ajax is choking on the encoding.
