Would only work if everyone used all the key words as hashtags, no?
Discussion
You could group different hashtags under keywords, plus have it include notes with certain keywords used.
nostr:note19n68789tmdsjy0x9ez370altrfllytdrrfkwr2zh477qt2vdx66s24h6nq have had this idea for a week or two, when I first discussed it on a nest π
So the relay operator would have to filter notes for a particular keyword or subset of keywords and overall relays become more niche?!
I think thatβs the natural flow of things. You donβt need 50 different overall relays as we do now. In the future I expect that we can select whichever relay(s) you want to post your note on
It will become more indexed and cohesive
We can already choose which relays we write and read from. That being said it should be automated, by relay operators only broadcasting notes that pertain to their niche. Right?!
I mean each individual note. You could select which relay you want to post it on 
I think you then run into the siloed, not decentralized issue. If I recall a post you made while back about removing Damus relay and not being able to see a bunch of people's posts was my inspiration to build nostr:npub16fcy8ynknssdv7s487nh4p2h4vr3aun64lpfea45d7h4sts9jheqevshgh since Damus relay is one server (literally).
