Right now, we're terrible at understanding what big groups of people want. And in a culture that prizes democracy, we can't be democratic unless we get better at understanding that.
What tools do leaders have now for understanding what groups want? Social media like Twitter or Reddit, surveys, and, of course, good old votes. But social media is mostly boasts and insults, nobody wants to take surveys (and we distrust survey results anyway), and meaningful votes or elections are infrequent and inconvenient.
The idea here is to create a social media platform that restricts users to only making suggestions, making counter-suggestions, and liking their favorite ideas. This platform would have the benefits of traditional social media--convenience, speed, accessibility--but apply them in a productive way. The goal is to create a constantly updating list of a given community's favorite ideas, ordered by their popularity, which leaders can use to directly develop new policies and projects.
