I don't think we need to appeal to absolutely *everyone* but we do need to appeal to a broader audience in general if we want Nostr to be the viable alternative everyone seems to want for it. I mean, even Bitcoin wouldn't have gotten anywhere if you didn't have people from all walks of life giving it a shot.
Plus, if all people talk about here is Bitcoin, libertarianism, agorism and that sort of thing, it ends up as an echo chamber, one that nobody except those crowds will *want* to join.
