If everyone chips in $1, and their $1 is split between all the things they’ve upvoted, isn’t the financial incentive to produce posts that are upvoted by people who don’t typically upvote? That actually seems like a pretty interesting incentive.
It makes me think, what if the upvote counter was the same, i.e. you have only one upvote per month, and it gets split between all upvoted posts. And maybe it would be nice if you could accumulate your upvotes over several months...
