for the most part, only crypto/bitcoin people grok it, so that's another narrowing of target audience.
in other words, the most likely places to get adoption for nostr will be forums that are about crypto. i mean, i was working for one company that wanted to get into nostr, from the web3 world, their strategy was not focused enough and last i heard they ran out of runway by focusing on stuff that wasn't going to get them users, and i told them over and over again, focus on nostr, but no dice.
it is a waste of time and energy trying to get people to use nostr when they don't understand PKI, and the centralized media have nothing to gain by promoting that, with the possible exception of xitter, where the problem is motivation to get off that clown show and into some authentic engagement.
people talk all the time about orange pilling and purple pilling but they are not focusing on people who actually will not be put off by the nsec thing and the vital importance of keeping their nsec safe from loss. as far as adoption goes, keeping it safe from loss is more important than keeping it safe from being snarfed by malware. once they are here, they can then easily move from one thing to the next, one simple single understanding is required.
any other ideas about how to bring people here are doomed to failure, except maybe for close friends who are expressing curiosity.
