There are some good social issue trackers like UserVoice and GetSatisfaction. Not only can people report what’s wrong or what they’d likte to see, but others can join in and vote for the issue. The idea has spread to most issue trackers too which is great. What I’m missing is the voting functionality on personal or corporate ideas. The whole voting concept should be made separate as a service. Maybe you want to decide on the next book to read, or the next game to play.
I want something like Evernote, but for lists where people can vote and help you prioritize. I could use it for my idea blog posts (like this one!) or at work where we come up with small projects. The list should be accessible from other systems. What would you use it for?
