I found Voice last night. It's similar to Jelly. Really well designed and just fun to use. You can ask questions to gather the public consensus (binary, multiple choice, rating).

Interesting concept. Pro tip: "give and gather opinions" does not sufficiently explain what this product actually does and therefore gives me little incentive to try it out. I had to dig into the about page at the very bottom to find this: Voice is a social polling platform. It allows anyone to quickly create and share surveys amongst a socially activated community of opinion makers.
