What would be really interesting is if they implemented a system like the old ESP game. For those unfamiliar, it was a collaborative game with strangers over the internet. You and your stranger partner are both shown the same digital image, and you have a textbox to enter tags for that image. There was a limited time and the goal was to get to a point where both of you had entered the same tag. Over time, as the database got trained, common tags such as girl, man, bird, etc were blacklisted, and so you and your partner had to come up with more informative tags to play the game.<p>Unfortunately, Google bought out the ESP game, and then after shut them down.
