These also exist. Some clients integrate DVM feeds (Amethyst, Primal). Some clients let you view specific relays as a feed (jumble, coracle, yakihonne), and relays can be created for any topic. You can even run one, either on your own hardware or on hosted instance. relay.tools is a simple way to get started.
I'd advise to get a broader taste of what Nostr offers, you seem to be unaware of a lot of what already exists. You may need to find a better client.
I think this conversation stopped being productive, because your answer will always be "that already exists somewhere." You're solving for technical completeness. I'm talking about why growth isn't happening even despite that completeness.
Yeah you're probably right, I offer the tools that already exist and you just move the goalposts. Do you have plans that could fix these issues you see? What concrete steps would fix this?
You could start building it with Shakespeare right now. shakespeare.diy
