But you see, intuitively we think that the number of upvotes in that model is a “dollar payout” for this post. But actually it isn’t! In a meme community, a post with 1000 upvotes would bring its author 1000 * (1/1000) = 1 dollar, but in a hardcore geek community it would be something like 1000 * 1 = 1000 dollars.
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...
If upvote count results in higher visibility, having visibility and payout governed by two different equations might make it harder to optimize, which seems good.
An actual debate on population control would be looking at reducing the number of children in the developed world even more, and discouraging suburban housing.
Nothing that a wealth tax on the current value of land won't fix. Make property taxes to the value of the number of people that land should support in a highrise configuration, and let the current owners pay it.
