I wasn't around for the superlinear rewards, but it sounds like it was a whole different ballgame.

with limited vote power deciding what to vote for is relatively more important then getting in instant votes.

Also there are a lot fewer votes that we get per day this is even more important than "back in the day."

There probably won't be a system that is entirely fair. And there probably won't be a way to keep those who want to abuse the system from doing so, but we can try to make it a good overall experience for most people and we'll be doing fine. We're still making more money posting here than they are over on facebook. :)
