Topics are only part of the equation & clearly a dominant part of home feeds. It's just not defined what the home feed topic is going to be at any given time, or for how long.
I am confident that if people can discover and explore different ways of browsing variously elevated content, they'll find things that interest them and be able to create their own home feeds and relay sets that resonate, whether that be by topics, personalities, or cooperative tasks. (Or many other possibilities)
Some examples:
This relay is a discovery stream of relatively random WoA filtered reposts:
wss://aplaceinthesun.nostr1.com
This one is 22 topics, also filtered:
wss://aquaticchickentheory.nostr1.com
This is a community of people:
wss://spatia-arcana.com
(
@Ryan has been testing... that's our thing-of-the-dayπ)
This is what's popular among that community:
wss://spatia-arcana.com/lux
This one is content fully curated by community members around one topic. It doesn't accept notes written there and all replies go to the authors' inboxes:
wss://spatia-arcana.com/favorites
This one is a loosely curated, topic-agnostic feed, with content voted in by a large group: wss://relays.land/spatianostra
It also functions with a no-write but outbox reply method (I am just a participant and advocate on this one.)
All of these things together create a little ecosystem that covers discovery, community vibe, trending, and topics. You'll see some content overlap. That's a result of the community still being rather small. Onboarding into the community is still best done through engagement, creating repoire, and getting invited... which can start in any of these feeds. The community can help itself to grow through members engaging in the discovery feeds and contributing to the curation efforts.
I haven't left you a lengthy, nuanced reply in a long time. I hope you'll hop on Jumble or Nosotros and explore these over the course of a few days, maybe give some thought to what I'm presenting here. (Take a break from the AI crazinessππ«) These are just mine (and only part of what I'm working at creating). Other people have different ideas and different patterns emerging from what they are building, too. Once we figure out a clean way to create sharable little samplers, this is going to be what makes Nostr sticky. I'm sure of it. Following people will be a much better experience when the emphasis on doing so is more aligned with a user's preferences rather than trying to either find needles in the haystack or conceding to what the dominant culture demands.
(I have to add that all the real work being done here is from
@fiatjaf @cloud fodder @david and
@Cody . I'm just using the tools available to me to create an example of what's possible.)
