I think every proposal I've read in this thread is incorrect. I think the platform shapes the debate. A crowd with megaphones will never be as good at decision-making as a jury. The websites we use are the platform (even if it's the same people in the crowd as the jury). The "megaphone platforms" (twitter/facebook) are very invigorating in the short-term but will inevitably drive people away. The next step is for a platform to be built that promotes and rewards the systematic advancement of filtering ideas (downvoting/upvoting being the most basic form of this). To a large extent, HN is superior to twitter because of this. Wikipedia is also a shining example of platform. This attention toward facebook is unwarranted, the platform will kill itself in 7 years. The important thing is building a new platform that incentivizes productive contribution rather than self-promotion or controversiality.
