I don't care what xo has to say. If s/he isn't willing to state what, if anything, s/he knows without making a game out of it, I can't take him seriously. S/he's just trying to play with us and, in so doing, make himself seem important and "in the know." If s/he was up front about whatever it is s/he might be claiming happened, that information could be challenged straight on, and that seems to be what xo is trying to avoid.
It's a child's game.
Jezebelle, Five years ago there was a poster named quidam who would post riddles. Although controversial, he was actually quite smart. There was some speculation it was William Safire or George Will. There was other negative speculation about him.
