ROFL, Anne! Never thought about the possible  "smell of one's own farts"  reaction to turning off comments.

The type of comments an image gets seems to depend on what gallery you post them. Poser and Bryce comments are more about the subject matter and overall feel of the image. Cinema and Max are usually much more critical and concentrate on technical flaws. Sort of art versus profession, where one has no limitations, and the other needs to handle whatever a client throws at him. When you think about it, the commercial artist is not only limited in subject matter, but he has to render it in very specific styles,  too.
