"Choose your own algorithm" will NEVER work on Nostr the way it works on Bluesky.

Smart platform-provided algorithmic feeds like those from X, TikTok or Instagram will NEVER work on Nostr.

Anything that requires filtering from a "global feed" of all notes and delivering that to specific users will never work on Nostr because there isn't and there cannot ever be a global feed on Nostr.

If that is what you think Nostr needs to be good and popular then you'll first have to destroy Nostr by turning it into something else, and then you can implement it.

The alternative is to create something new, a new way of doing discovery, something that actually works nicely within the Nostr constraints, something that actually only works on Nostr because only Nostr has these distributed independent servers with specific owners, specific rules, different users, personalities and preferences.
