On #NewSteem it matters what you vote on. That is Proof-of-Brain working.

Not really. If I vote on something and think it's good.. and the crowd doesn't agree, I am now throwing my vote away.

You have in essence created a system where I will vote only on things that already have votes, regardless of quality. Theoretically anyway..

If no one has voted on it, then there's no incentive to be the first. Well done for creating a hive mind instead of rewarding the individual choice of a steemian. That's not quite a proof of brain so much as a proof of hivemind.
