This indeed!

One day I had an idea for a new type of visual UX for a nostr client just like something you mentioned!

So like, every note is a bubble that can be inflated and the more it expands the more 'lighter' and up on the feed it goes, like a baloon 🎈, but since it would constantly lose 'air' it would need more engagement to stay up (more zap, reactions, comment). In this method notes would not trend statically for longer if they are not constantly promoted.

Imagine it like notes underwater that needs a push to not sink into the oblivion.. negative sinks, positivity raise to the top.
