Months later...maybe it should be noted that at the time, I dropped a note to the guy, asking him what was up. He claimed not to have noticed it on his read through, questioned whether it had been there at the time, but did post a (IMHO rather too mild) "I think that was problematic" sometime before she deleted everything.

I had an extended discussion with him, wherein he came across to me as being rather more concerned with the pile-on than the original fail. I suspect he and I will continue to talk about this sort of thing in future iterations. (As far as I'm concerned, it's a conversation I've been having with him and a few other people since back on Usenet, and one of the reasons I dropped out of a certain newsgroup and ended up in alt.poly.)
