If the only thing you know is bitcointwitter, nostr is fine, you have all the slogans and "memes" here. Maybe even Meshtastic, Christian community too. Beyond that you'll struggle to find engagement really..... For now. Who knows 

 Christian community is surprisingly thin, here. Hope it gets better with communities. 

 Perhaps so, but it is still relatively active compared to any other subculture / circles. 

 Not saying much. 

 Yeah that's pretty much what I mean lol
