if the critiquer doesnt post anything, you dont have a way to value the critique.
If the person posting knows his/her stuff, that makes the critique all the more valuable. If the stuff is crap, then the critique has less (but not none) merit.
if you get a critique from Robert Sanders or Christian or Chung etc, their stuff speaks for itself and so does the advice from them.
If JohnQ GWC writes what he thinks, it may or may not be valid, and the quality of his/her image is a clue to the validity of their comments.
