The Amazon Mechanical Turk is a cool system (a friend works on it). So I went through to see what it looks like.
One customer is A9 - they have visual Yellow Pages and need the community to vote on the best image among several for business storefronts.
I was suprised that my third HIT was a request to pick the best picture for "US Government Seattle". My choices were either a collosal two layer cement highway section, surrounded by rubble or a tree. I chose the tree.
