I can provide some more info on the survey stuff.
Many years ago (1998-99) my wife was chosen by
http://my.kninc.net/Login.aspxTo take surveys. The only incentive they were offering was a free WebTV + keyboard + free service. Everything was free, mind you, as long as you took the surveys in a timely fashion. Otherwise, they'd drop you and ask you to return the equipment. Supposedly, after three years, you'd be able to keep everything.
Anyway, we had no need for silly WebTV (we had a proper computer and dial-up), but being the dorks that we were, we thought that it would be neat to see how WebTV enhanced the television.
Well, digital cable was not widespread at the time, and even when it was more readily available, you had to pay extra for it. So, we actually had a blast with WebTV since it provided on-screen info and schedules. It worked very well, actually.
Soon digital cable was the norm and there was no need for WebTV.
But we were still taking those stupid surveys. At least 2 / week. Lots of organizations used Knowledge Networks services, and sometimes you were told who commissioned the survey you were taking.
99% of the time it was typical market research garbage.
Sometimes, especially around elections, big news stations would use surveys to gauge the sentiment towards candidates.
Sometimes the surveys seemed to be for public policy. At other times, it seemed like it might be for academic research (this was very rare, though).
What I learned from this experience was that surveying was big busisness and that many organizations (from news organizations, academic researchers, public policy advocates, market researchers from corporations) must have paid a lot of money for Knowledge Network's services.
In order to obtain a representative sample for a survey, you have to either use the phone or the internet. Since WebTv's were distributed for free, it ensured that folks who might otherwise have been excluded from the surveys were included. It reminded us of the Nielson "boxes" that folks got. A kid I knew in high school was in the Nielson survey.
Anyway, long story short, I hated 99.999% of the surveys I took and purposely answered to keep things as short as possible. "Do you enjoy any of the following beverages?" No. "Bottled water, then?" No.
