Try out Nostr.kiwi, there is community for a lot of different things. Twatter like clients are very specific so it’s hard to curate different content (unless you follow a set of different people and look at their post, which is time consuming). Hashtags help a lot too.

I myself did a bot that shares hashtags for Hispanic people everytime #hispano is used nostr:npub1s0n9cxltdgah4tm8vnpt9mg0eten2qla93x69g8yr6xj8tdt8q5qe5yxse but there a tons of different things other than Bitcoin and Nostr related
