Tom,
Yes, and no.
I think most, if not all, appreciate your participation and contributions to GCA.com, and as such they don't want to be critical and/or offend you.
To a degree, I think that's good manners.
Sort of like not telling the hostess that the food wasn't up to par.
Yet, if you don't tell the hostess that the food was mediocre, you reinforce her belief that she prepared a delicious meal, hence she'll not make any improvements in the kitchen, so it's a delicate balance between good manners and honest CONSTRUCTIVE criticism.
Secondly, most are afraid to offer a candid opinion due to your credentials and track record.
They don't want to become the slain messenger.
Third, would you view a critique as constructive ?
No one likes criticism, yet, without constructive criticism, progress is impossible.
Can you, upon reading a criticism, take a step back and evaluate the remarks objectively, without immediately getting defensive ?
It's not easy to do, and anyone who's been married for a few years clearly understands the difficulty and the dilemma.
The fact that you raised the question leads me to believe that intellectually, you understand all of the above.
The other difficult aspect is the "unknown" aspects of your work.
For example, I'm no fan of the second green at Sebonack.
I've never experienced a dire event on that green, but, I believe it's "excessive" in terms of concept and play.
However, any criticism I'd offer might be misdirected.
I'd love to engage in discussions about specific holes or features, but the data base I have is limited, and as such, without knowing all the facts, I'm reluctant to engage in discussions, and I would imagine that most feel the same way.
