Once again, you're ignoring that not everyone (in fact, I'd dare say most people) don't post art to get comments. Most people in the fandom post art so that people will buy that art or buy commissions.
I think this would be an excellent topic for a future survey. (It should probably be done both at conventions and online, to decrease bias towards professional or amateur artists.)
