invoke
invoke is one of the major 3rd party survey and customer satisfaction research groups....they are legit. The thing I would balk at is in order to participate in the paid survey they want you to "qualify" with a preliminary survey which 99% of people will fill out and get paid nothing....only the handpicked people with the "correct" attitude in their answers will get to move on to the paid market research study....no doubt filled with people who love Airtran and SW and think they do no wrong.
I have done a couple of 2 hour radio and music surveys....you had to pick the target station as your favorite and like all the music they play....just to qualify....then they paid you $150 to rate songs so they could adjust their tired playlist. (or convince themselves that it is fine the way it is).
The only way to beat these staged opinion polls is to lie in the initial survey, get chosen for the real survey, then tell it like it is.
