Nostr is still very conceptual - devs are building on it, so its ok not to fully comprehend it - i don't think its possible to have a binary definition on Nostr yet. But having devs explain this to the masses of different target audience is pretty powerful - and diff devs have diff strength and ways of explaining - Pablo's conceptual, Verbiricha has a nice story telling flow, Hodlbod is like your fav professor, Jeff gives you the dotted line hints - and often times audience are empowered to not just use but to explore and tell their friends and neighbours. Now while I did not spell it out, everything i listed is a form of marketing, not the loud speaker version, just the more targeted, cost efficient, exciting ones. These are some of the few ways Nostr can get rooted and spread further. And while I am not a dev, I have reached out to devs and tried to help in any way I know how. I would encourage you to do the same. All of us have hell to deal with everyday and dealing with more downers is no fun. Def stay here. And build.
