I would love something that optimizes for curiosity, instead of engagement. I wonder sometimes what signals we could take from a social network to promote things that spark curiosity and don't play on anxiety, create flame wars, etc... And if such a thing is even monetizable or worth building. Hacker news is the closest thing, but even here clickbait sometimes happens :)
