Cool and usefull project and quite an impressive amount of working code in a relatively short amount of time.
I thought of something that could potentially make it even more popular. Allow the creator of the poll to add a prize in SBD that will be paid to a randomly chosen voter.

My first thought was to pick a random winner among the ones that voted for the winning option, but that would create an unfortunate anchoring of votes where everyone would end up voting for the option they see being most likely to win. So a randomly selected winner would probably work better ;-)

With the Hack-a-thon well over, I have to ask if you considered entering the Byteball Use-a-Thon with that python library you earlier mentioned you had started working on. It would make a brilliant addition on top of/next to the JavaScript library that @fabien created? There's still plenty of time to join and take a shot at one of the prizes ;-)
