What’s the practical application of this? It makes sense in chess where you have two players using the same rules, so a comparison makes sense. But is Postgres a better database than Redis? Is The Godfather a better film than Lord of the Rings? These questions make no sense. Political candidates can’t get an increased value simply for being less popular.

So is the idea that you use this in a very technical space for, say, ranking jobs in a queue? Or is it intended for an e-commerce site to order by product ratings?
