I doubt if anything anyone said here is keeping him away--he always has had a thick skin and can dish it out as well as take it.
This is my gut feeling too. I'd expect a can of verbal "whoop-ass", and opportunity to learn something if it was something i said. But, on the off chance, i just wanted it out there. I have a great deal of respect for his experience and knowledge, and like the other posters here i look forward to, and currently miss his posts.
