I wrote a few posts on this when I first joined nostr. The idea is for users to curate 'filters' of ways to view/reduce npise in the global feed. These filters could be keyword based, hashtag based, user based etc. But the key is that I can make this filter shareable to other like minded people and its transparent what is going on. No algos.
So maybe if someone is new to nostr they can select a couple of cool filters and then they follow those users
