One feed* just doesn't make any sense
Look at reddit- the most common alternate accounts are either throwaways or novelty accounts. Nostr has plenty of both. These don't serve the purpose of splitting interests as much as specifying a "role" or "personality," or maintaining privacy. Look at nostr:nprofile1qqs04xzt6ldm9qhs0ctw0t58kf4z57umjzmjg6jywu0seadwtqqc75sprfmhxue69uhhq7tjv9kkjepwve5kzar2v9nzucm0d5hsz9thwden5te0wfjkccte9ejxzmt4wvhxjme0qythwumn8ghj7un9d3shjtnswf5k6ctv9ehx2ap0y8qdrm - He has two accounts. One is personal about climbing and the other represents the "developer/influencer Pablo".
Is this beneficial for him as a user? Probably
Is it ideal? I would argue not for me, and likely not for others. Can't speak for Pablo but I think Nostr can offer more flexibility that would defeat this inherently bastardized, single-feed structure.
Nostr says "discovery is a manual feature" and to that I say "feeds are the garbage can for discovery". I leverage my feed to discover often, so it is not inherently a problem of feeds themselves. The problem is single-feed silos.
So we can manually segregate feeds with a tool like Listr which integrates with Amethyst.
But this process is pretty much the same as it was 3 years ago. Unless another client is offering better list curation. I haven't seen anything change in this regard. There is a bounty out for CRUD lists in amethyst and I really hope someone can pick up that lead. Not here to complain, just my two cents.
The resolution would be native list management in my eyes. Splitting the user between tools does not feel intuitive with an app like amethyst. Just about everything else is miles ahead.
Our feeds should be able to designate their own relays in my opinion. Let us filter by relay first, then by users, then by content.
