Somewhere, I firmly believe a marketing firm is creating all of these surveys. The information gathered can be mind blowing. Starting not with your answers, but your IP, they can start with location mapping, then with other factors they can track such as browsers, access type (PC, mobile, etc) they can match these up with specific answers to start to create pattern mapping of areas and demographics that would foster (and could be manipulated by) certain thought patterns and advertising.
When you look at the questions in this light and consider even the most basic info they can tie to it from your IP (then combine it in mass), it is pretty cool.
IF it is being used this way.
