I sort of understand the rant. I'm more likely to take the advice of someone who has posted images. Without seeing what they can do, it's difficult to know how much skepticism to attach to their "expertise". But, there are certain people who i always heed, as I've seen the quality of their work.
I post images for feedback (not ego stroking), especially if I'm doing work I'm unsure of, or new at. I've been lucky to get a lot of help when starting with bromoil and liquid emulsions.
