Okay I'm imagining a public debate platform based on twitter. You set up a time, a topic and a hashtag. Then people can log in with their twitter accounts and say something about the topic. When a thing is tweeted it shows up as a bubble floating at random around the screen. When you hover on the bubble it stops so you can read it. Then you have the option to retweet it . If you retweet it it the bubble get's bigger for you and everyone else viewing. You can tweet a new point, or you can just read and retweet what you agree with. The effect of this is a mass public discourse where thousands of people are 'heard' at the same time in real time.
The best of the best from the minds at TIO.
