Change the voting algorithm from full linear to anything but full linear and possibly n2.
Non linear voting algorithm incentives people not to split their vote and thus concentrate the votes on the most valuable content and people. Each of us are seeking the very most valuable information, not second best.
It also changes a lot of other dynamics which I think are beneficial to everyone. I just wanted to make sure it was still on your radars. I might expend on this subject in a future post.
This change should only be seek if it benefit the whole platform obviously.
I wrote a bit more on the subject here.
