To criticise

John, I saw your comment earlier but was just on my way out the door, so I didn't have time to say anything... and you've gone and deleted it, probably thinking I was deliberately ignoring you, because you're a nutter

Originally this was just a toss-off reply to a wanker on another site (you could probably guess which) and it's possibly not going to evolve into anything more than that but I put it here to let it breathe and see if it was worth revisiting in a while.  I forget the specifics of what you wrote so if you're of a mind to, I'd be grateful if you'd let me know.
