Well thanks for telling me stuff that I already obviously know.
Actually you obviously DON’T know it. If you filled out that quiz you’d tell them all kinds of interesting stuff about yourself, they’ll know if you drink soda and what your favorite brand is, your brand of toothpaste, jeans or dockers, the whole gamut (and note, none of the questions seem to relate to any of that stuff). Of course the questions are helped out by the fact that as soon as you hit the quiz they know your computer type, OS, browser, and every website you’ve hit since starting the browser session (and that’s with cookies turned off), all of which they can relate even tighter to your products and brands. That’s the modern era of data mining, they’ve got the cross relational data sliced thin and accurate.
