This is exactly what I want. The purpose of Jumble is to better browse relay content, and I hope to see more unique and interesting relays emerge. Nostr is a decentralized network and shouldn't be controlled by a few giant relays.
Of course, I won’t stop you from forking Jumble if you'd like. Everything is free and open.
I don't have the time and energy to code, all I can do is point out that someone should do it.
Making a more decentralized global feed is a really hard problem. The best existing solution is the op_return function in Bitcoin and some other currencies. I think this image already captures how to make nostr highly effective
