I don't want to be mean by mentioning it again and again but it is the most common complaint about nostr. And it sort of feels like that problem is never really taken seriously.
Not many clients has really thought about catering to another demographic besides bitcointwitter expats. Nos social and voyage might be the only examples I know of.
The user recommendations at onboarding is probably a bigger problem than most think it is lol. imo imo
Imagine having this 'no bitcoin chat' relay set up as a choice at onboarding. You're timeline might be slow, but that is actually preferable for a lot of people to a barrage of bitcoinisms.
