So, back when I worked on the Google indexing team, Bing had some Flash games that would automatically fire off Bing searches in an iframe for every puzzle guess you made. They'd give you some points that you could redeem for prizes. I suspected a major goal for the games was to artificially inflate Bing's search market share numbers, but maybe also to gather data for machine learning and/or old-fashioned statistical analysis. I was curious... and we at Google were careful about machine learning because we knew that, for instance, if you had an algorithm that internally rewrote every query by appending "breast", it would almost certainly cause the click-through rates to skyrocket while harming search quality. So, on my own time on my own computer, I used these Flash games as a typing tutor to re-learn QWERTY keyboard layout, and would often append "breast" to the in-game searches. I didn't learning anything from my poking around, though I did get enough points to get 2 Coleman tents, a mult-tool, a external hard disk, a record player, a bunch of DVDs, and a few other freebies from Bing with all of my game points.
