If you meant how do I discover content, through searching tags and through content shared by people I'm already following. I don't give much about "trending" content on some of the apps since those oddly show the same bunch of people every day with 1 zap or 10 zaps or 1 comment or 10 comments.

The best content discovery is through tag searches and by growing your network on nostr.
