There is not #theNostr..
..there are as many nostr as many npubs are utilising it multiplied for every client that is running the protocol and on which you can access with your keys.
Every npub has different feed, even if could look similar, it's not, and it's determined by any npub single choices, of following, of relay connections and on settings about your client.
.. you are your algo, means also you are your own #Nostr, and every feed is probably like a snow flake.
You can verify it just by opening a client with different public keys that are not yours, and the same public keys on different clients..
.. sonif your feed is boring, you don't find signal, you alhave the impression "here it's all about same people talking about bitcoin, steaks, footstr and nostr itself" the problem isn't #theNostr, is the version you created by yourself that's not appealing enough, it's your algo, it's you. 🫂💜
