Your page is a good idea (one i've been too lazy to implement) and it is useful in collecting realistic bf% pics from around the web. However, i have some bones to pick as well:
1) You claim to have wanted to look like a bodybuilder and you know your DEXA bf%... and yet you don't seem to have included your own pic.
2) i suspect you don't have the express written consent of Fox and Major League Baseball to post said pics (though you do link back to the source in most (all?) cases ) which is good).
3) Your
color commentary is both not very informative, and, imho, not too well informed. For example, you don't seem to be aware of (or at least you never mention) that muscle mass is an important determinant in what people look like at different body-fat levels. For example the bb.com guy who goes from 17 -14.5 who you deem "a real headscratcher". The guy isn't ripped (i don't actually know the terminology), it's just that he's got some decent muscle mass (more in the after pic too). And in that 2nd pic (looking at that vein on his right shoulder) he also prob. pumped up some. This is also the issue with your 17% woman. The reason why her legs and obliques look that way is because she lifts, probably quite a lot, and has some muscles in there. (and/or photoshop).
3.5) A second issue in the commentary department but i want to call it out in its own point: you're making fun of these people to some degree. Why? you seem to be interested enough in the subject to put together a page so why have lines like this: "You would never guess that this guy is above 20% bodyfat. That’s probably why he looks so sad." ? The tone is needlessly disrespectful of your subjects who put up pics of themselves in their underwear on the web; especially given points #2 and #1.
