I agree with Kalen on this (but perhaps not the part about you having a preconceived notion).
I've thanked, sometimes several times, almost every single architect that posts on here for their contributions (as well as some of the very knowledgable non-professionals). To me it's pretty simple:
If I was a successful film director or published novelist, I'm not sure I would be taking the time -- any time at all -- to debate and discuss and butt-heads with a group of amateurs, especially if some of them continually disparaged my work or technical aspects of it with so little information to go on. What in the hell would I get out of it?
So, whatever the reasons the architects themselves give for participating here, what I tend to see is their generosity and their love of golf course architecture. Jeff B, Tom D, Scott W, Mike Y, Mike N, Forrest R [edit: and Paul C, etc etc] all warrant our genuine thanks, and a regard/respect for their opinions. That some of them don't get that is a real shame, but it doesn't seem right to blame the ones who do for our failings.
