What I like to see is a #nostr Client where you can create your own lists of people you follow (with the right relays ‘attached’). This way a user can quickly switch to a list where he can see all posts regarding an event (e.g. nostrica in my example).
I started to design this idea over the weekend:
Topics should not be tied to People. Picturing a topic by a list of follows is not ideal. A better model is Slack's workspaces, where the user mentally shifts into a community/topic. That can be achieved with a relay set switch for read and write. In that way, you dont get your Bitcoin follows posting about their diets.
