Articles cannot be downvoted by others, regardless of reputation (sounds good but we need some enforcement mechanism to remove scams and illicit material).

All votes carry equal weight (this should be a no-brainer, but we would need some sort of automated "proof-of-brain" and protection against people controlling hoards of sock-puppets).

Curator payouts are equally divided among all curators (lowering the minimum payout to 0.001 steem and removing the "timing" bonus would fix this).

Good ideas!
