That's an interesting question.

If every user has a different preferred post ordering

This may be a little closer to what SN was like before trust was removed in December. I'm no engineer, but it seems like you couldn't achieve personalized ranking solely by using sats.

Currently on SN, if you zap a post and refresh the home page, you can see it move up the rankings. Whatever else it is, this seems like a transparent system.

I think that personalized front pages would necessarily be more opaque as to what kind of posts reach the front page.

I wonder if it is a necessary side effect of money as the moderator that it produces global ordering.
