Right, but I've seen the survey, and it pops up. That's how it's implemented.
I don't think they've been very widely used as yet, I only very occasionally run into them.
Supposedly publishers are paid, but I have no idea how it works. I guess you have to apply:
From what it says though, it wants news publishers and "premium" publishers, so they're probably thinking it only makes sense on those sites where they're likely to get a lot of surveys.
