The feed ranking algorithm I implemented for LinkLonk does reduce the weight of your vote the more you vote.

If I upvote what you upvoted then your votes get more weight for me.

This incentivizes each user to upvote what they truly found useful for themselves as opposed to the current incentives of social media which makes you upvote/like the stuff you want others to see.
