Okay sorry to be soooo normie here, but even the word “keys” is very specific to a set of people. I’m sure it can be inferred what it means, but I could also see people being like, is that a password, a physical drive, why are they calling it keys, etc? I even think relays kind of needs to be explained, I didn’t exactly understand them when I first started. What would attract me would be saying that my data is not owned by a centralized corporation. there are a bunch of small entities that can hold the data in nostr, but it’s up to me in which entities it’s held. I am 100% in control of my profile, what I see, where my data is being held. Nobody but me can modify my speech or silence me (Which is essentially what you said, in more “normie” terms)
