I don't care that much about publicly posted comments.
a) they are public, i.e. you don't have to have any qualifications to leave them beyond a valid email address.
They are public, i.e. they are a form of grandstanding wherein someone can take the traffic headed to your work and do a little show for them, like people who clean your windshield at at traffic light.
I have really, really good luck with comments most times. The paper I have here has a string of thoughtful comments from some great people. Other sites, though, popularity outweighs artistry 1,000,000 to 1. When people have a little number signifying how many comments they have made, the number sometimes becomes far more important to them than the comments themselves.
As for serious, 'heads-up' quality input, I really appreciate the emails I get. Because they aren't public, the sender has no motive besides giving me their opinion and suggestions. When you get a "that is really nice" or "that sucks" email you have to sit back and listen. I have received a few dozen over the years and they have all been very satisfying.
Don't sweat public feedback. People who leave unfair comments are just hanging a sign around their own necks, not yours.
