I like to think how this could change how ideas are spread and organizing. I imagine something like google hangout but with 100 like minded people all present at the same time discussing a common interest, with something like a real time voting mechanism in place so that those with (presumably) better ideas are more likely to be heard.
In one example I'm imagining a city council meeting, where anyone who just has the time to log in can take part. And then I realize that maybe this would lead to horrible popular ideas being more easily spread.
