With respect, that link didn't add very much and the guy's a foul mouthed jerk, to boot.
This is an incredible amount of work and dedication, but you'd never know it by the blogger's flippant attitude. Forgive me if I missed an "inside joke" here but...jeez. "Just going to be huge prints of Americans"...I'm Canadian and I think that's disrespectful.
The blogger's a rude little oik, true, but it's the video downpage where the "American Portrait Project" is explained in depth. Try that and ignore the text, OK?
