Yeah that can be nice but both are good. Global is the only way for Nostr to be alive and interesting...this is how all the competing or similar tech works too.
Once you get algorithms and other nonsense, This will be a crappy place like Twitter. Twitter refugees need to stay on Twitter and stop poisoning the well
I don't care. Nostr needs to have all kind of options, clients with algorithms and without.
I have mute option, so why care about these things?
The fact that competitors didn't do it yet speaks on its complexity and desire for it. Better Competing tech has been around for over 10 years and dont have that feature yet.
