Most new organizations are also general-purpose, meaning the organization will cover everything from politics to sports to tech to finance to gossip. My assertion is that trying to be all things to all people leads us into impossible-to-moderate scenarios even before you look at the motivation/resources available with which to perform said moderation.
I'm proposing approaching the US code and other bodies of law (and associated jurisprudence) as a Wiki and seeing what happens. I propose that this could be an improvement over the whole representative democracy approach.
