I don't know - peer pressure (or just fear of appearing stupid) can be a pretty compelling thing. I would imagine it would take a fairly bold poster to speak out here against a photograph from Shel or Frank, say, especially after a dozen or so posts saying "stunning!", "brilliant!", and the like.
If I see a photo I don't like but have something constructive to say, I'll say it. I think that's been the case for (occasional) photos by Shel and Frank in the past. Generally I either like a photo and know why or don't like a photo and can't see a simple way of improving it, though. (Apart from "learn to focus!", or whatever... :-P )
