Same, on this one I was able to listen to music or open up a twitch.tv stream while waiting 10 seconds between answers. On a different note I did over $53 worth of the material hit and am one of the ones that haven't got paid :~/ luckily I snapped a screenshot a little bit before quitting, that should help her sort it out a bit!
I did this one all the way through. With a couple of breaks, it took me nearly 3 hours. I knew from the beginning it wouldn't really be "worth it', but on the HIT they said they would be willing to pay more but they can't since I guess they can't afford it. They're grad students.. I thought I'd be nice and help them out and not complain about the money. Pretty ridiculous though. Now I'm a bit worried about the payment. I didn't get a code, instead I got an email to contact them to let them know I completed the survey. Kinda weird. Guess I just gotta wait to see what happens.
