Yeah, got told about this. My only hiccup with it is the resolution. Some stuff that I take (and I'm sure others) looks fantastic at 4000px wide. But when it gets shrunk to 1000 or so, it starts looking awful. Everything that made the photo great kind of folds up and washes into itself. So...when thinking about shooting for this site, instead of thinking broad good shots, I'm starting to shoot for the crop (so I can post 1:1, pixel for pixel)...which is a terrible idea on so many levels for so many reasons.
Not that there needs to be anything done about it. It's a real constraint of the 'net for sure. But it does twist things a little.
