I would one up that suggestion : what could be awesome would be to allow users to choose which sorting algorithm they use, and possibly tweak it. This would allow people to share the sorting logic they like, and there would be no trust issue, since you can verify the logic is respected by changing it.
Not sure how realistic this proposal is, though, because this could lead to performance issues if users submit too complicated sorting logic, which could be exploited to DoS an instance. On the other hand, it could be solved with a timeout mechanism : "if your query takes more than 100 ms to load, we kill it". And also, you can't just let users run arbitrary SQL, obviously, so this would require to implement some sort of meta-language safely transpiled, this would be the real challenge.
Oh really? Awesome. I'm still not going to use a generalist social network, but they're doing it right. :)
Yeah, indeed. My taste for tinkering may be showing, I should acknowledge it's not something widespread. π
