IMO search would make Nostr better than Twitter. But it seems like most users don't want their posts searched. Mastodon is a good example of that. If letr.co works out, I'll use that. Otherwise substack or ghost.
Nostr search works good right? Ditto and Nostr.band
It's good enough for now. But no metadata options for sorting (by date, by duration). The devs are probably afraid of creating a mix of 4chan and piratebay
