I had a similar idea when trying to vote with friends on where to go out on a Friday evening (which bar). We used another tool that got the job done. The UI of yours is nicer, but I don't want to create an account for such a one off event. At least, make people fill the poll creation form before asking for sign-up. Make sign up optional, just to get the results by email. Maybe add a web notification button to get updates this way without sign-up.
