It's amazing how many trolls are against innovation. I realized that an important event was when we stopped having downvotes accross the internet. That means that there's no real way to discourage bad behaviour which is at the heart of all good reputation systems. Also it is asymmetric. The elites have means to discourage bad behaviour in the population. But the population has little means to discourage bad behaviour in the elites. A good reputation system would help fix this. Of course that, too, has to get over the innovation barrier.
