I read the previous post the same way as Frances; it didn’t strike me as an embarrassing thing to think or post. Public figure discusses something, you’ve just published a book directly relevant to what he’s discussing, so why not join the two? It’s a good thing for academics to be doing; if there were more of it, we might not hear the “ivory tower” jibes so often. Which was why I googled around for a few minutes to see if I could help… I’d never known who he was before yesterday, so there was no stalkerish intent.
That said, deleting a minor passing request seems a far cry from deleting a more developed piece.
