I've never bothered joining that site (can't stand the forum interface he uses, looks like something out of 1998), but one thing I really don't understand about that guy is what he deems a positive (green) and a negative (red) in his little charts. It really jumped out on me on his new comparison of 70-200mm f/2.8 zooms:
Canon EF 70-200mm F2.8 L IS USM Lens Review: 2. Compared to...: Digital Photography Review
WTF...$1600-1700 for a lens isn't a negative when the two you're comparing them to are $700-800? I almost don't need to read any further after seeing the price since it's such a huge negative.
It also drove me up a wall when he showed two versions of the Nikon D200's jpeg performance; one at the default setting (extremely soft and blurry), the other with boosted sharpness to make it look better. Yet he didn't bother to do that with the K10D. He just simply brings up the K10D's poor jpeg performance every chance he gets.
I agree, that site is good to use as a comparison tool (and his product pics) and not much else.
