Reward of a post is weighted by
net-positive-votes * net-positive-votes. So it’s likely that voting on a post which already has high net-votes will bring you more reward.
So there's actually no incentive to find quality content and be the first to upvote it, but only to enforce the status-quo? That's bad. Is it by design or by accident?
That is my observation too. I hope this is not going to be the case.
