Shameless plug: I recently needed a super simple, clean and fast way to create a poll. Since I didn't find anything to fulfill my requirements, I built my own - http://tally.tl/
If there was an option in Tally to hide votes so they don't influence decisions, it would be more useful. We used it at Techstars recently and didn't find the results very accurate. That said, it's very slick and simple, which I really liked.
That's a very good point Patrick. It was intentional because I didn't want to add extra buttons and clutter the interface, but I might rethink it. It's always tricky to add functionality without sacrificing simplicity.
What about http://strawpoll.me/ ? Is there something that your site does differently than that one? Heres the same poll at strawpoll: http://strawpoll.me/2716564 so you can compare. This site is commonly used at twitch.tv so that the streamer can ask the viewers a question, all results update in real-time. I have seen thousands of people use it simultaneously with no problem.
What I really need from straw poll is an option for better voting methods, if we're deciding between more than three choices for streaming we always need to use instant runoff to get an accurate measurement of what people want to watch. Something popular like Schultze voting (maybe implemented with sliders from one to ten instead of entering rank numbers; so it stays as idiot-proof as strawpoll.me)
It's not perfect if you're worried about people voting more than once. We tried doing an office poll about something people held strong opinions about -- what video game to bring in for an office tournament -- and within twenty minutes, coworkers had rewritten ballot stuffing scripts in bash, PHP, and Python.
Not to mention that you can submit multiple votes by opening the page in an incognito window in Chrome.
And that's the poll question I wanted to ask: http://tally.tl/GQDy3
