> Art? Any criticism of art is always inherently subjective, it can easily be blown off as the critic not getting it, not liking that style of art, etc.

I chose Art as an example simply because it was the farthest thing from a technical field and thus refutes the assertion that "direct criticism" in non-technical realms is rare.

All I am stating is that criticism of work is a central component of art (and other non-tech domains). It is not "rare".

You are saying that art criticism is "subjective" and that therefore it "doesn't count"-- that's your personal opinion that I don't care to argue about. Subjectivity is as much a part of the human experience as anything else.
