One primal feature that stands out is the ability to filter the home feed to the notes "Most-zapped 4h". But unfortunately, it's broken as content does not get updated! It seems to be loading only the first time and is changing the content never again.
Other available feeds like "Trending 24h" seem to update better. Nevertheless, as #Nostr is still early the trending feed is not helpful, because big account GM notes are nice but not valuable to me.
Best Nostr filter is any variation of Most-zapped per amount and per number of zapper!
Please Primal get the updates fixed and please a open source android nostr client (npub1nz6…0w5y) and damus (npub18m7…q955) provide a filter to most zapped content as well!
