Wouldn't proof of stake be much more promising? 1) Start off with a trusted group of people (stakeholders) 2) Set up an invite-only system 3) Inviting someone means sharing some stake (i.e. some reputation) with them 4) To post you need some minimum amount of stake 5) With every post that's not downvoted into oblivion you increase your stake until you reach a certain equilibrium point. (So there's a limit and it's not about gaining status points.) 6) Posts that are downvoted into oblivion will cause their authors to lose some stake.
