To my knowledge, range voting is the most optimal way to run a single-winner election or poll. Aside from being dead simple (e.g. score each choice 0-9, highest sum wins) it's staggeringly unmatched in computer simulations calculating Bayesian regret compared to all other systems regardless of voter utility, strategy, honesty, ignorance, or noise.
Is there a web app for conducting polls with good support for range/score voting? A self-hosted solution is perfectly fine, although unnecessary. Any required architecture or platform will do.
Google has lead me to SurveyMonkey, PollDaddy, EasyPolls, StrawPoll, and none had this. Some came close but the votes weren't kept secret. StrawPoll allows approval voting, which is at least a step in the right direction but the results should be hidden until finished.
BetterPolls has the best implementation I've found but seems relatively small and lacks features such as optional single-IP tallying. (Although it does have a mild captcha.) OAuth login support (e.g. Google+, Facebook) would be ideal. I know it's impossible to stop all ballot stuffing but it would be great to see an app for this superior system, particularly for fast and easy straw polls.
