Tried it, only to learn that I’m a very, very poor match for most surveys. The field appears to be glutted with my fellow retirees, for one thing. My consumer habits don’t help, either, as I tend to be frugal-ish.
The time it took to find any survey that would take me, plus the fact that most of them bored me, and none of those I found paid very much, turned me off.
Other folks in different demographics, and with different habits, might fare much better.
