A while back I designed a happiness meter for user’s notes. The idea is that you could rank notes based on how they made you feel to show more or less of those.

But, this could be modified to act as a profile ranker. The more notes you mark positively, the more your feed prioritizes that person. And the opposite is true. Basically, if you wanted to show up in people’s feeds consistently, you wouldn’t share anything overly negative as that would decrease the likelihood of your notes being seen.

And since this is per individual, others can’t manipulate it. Only your rating counts.
