Indeed; tickbox multi-choice questions can be v. quick to fill out.
I’m only throwing out suggestions for “good questions to asl, ASSUMING no problems with people answering them all”. 
OTOH, I never participate in polls, because they’re such a vacuous waste of space. “Do you prefer Java or C++?”, “Is Java: slow, medium, fast?”, “Who’s your favourite Spice Girl?”.
99.99999999% of website polls are complete crap, and sound like something that a 6-year old child came up with on a hot, boring sunday afternoon. Like popups, pop-unders, flashing “you have mail, click here” pages etc, I’ve learnt to mentally filter out polls at an almost subconscious level ;D … thankfully - since unlike popups/unders/etc Mozilla can’t automatically get rid of them for you
