A single feed per user is a limitation created by social platforms. If it were sufficient people wouldn’t need to have multiple social accounts for various content. I would like a Nostr client with multi-feeds. The typical Twitter type feed, long-form content, photo galleries, and automated content from apps. These could include such as music tracks playing, videos watched, games, scores, steps walked, etc. that are tagged and can be filtered.
One person’s noise is another person’s signal.
