Sorry for being so hard on it. I looked at the intro page again and see now that it's not what I was thinking, where you have a large database of good photos with known dates it can choose from, instead each day your curate (I assume) a few photos for everyone to try and compare results (for the same photos). So it's not just a matter of letting someone play again, because currently they would get the same five photos. I took it to be something like the classic "Am I hot or not?" with a database of tons of photos.
