You may also interact with countless bots without ever knowing, because creating fake identities is free.
I really don’t care about loosing my identity
Fair, some people value their identity.
how decentralized is it when your identity is “centralized” in your key pair?
For average people nothing changes, the app can hold their key for them and even offer email recovery.
On top of that so many people regularly change their display names on social media for vanity and expression purposes that I can’t reliably use them anyways for recognizing accounts.
That’s something having signatures and a web of trust solves.
Besides, you fail to see another problem: Whichever centralized, federated site you use can manipulate anything you read and publish.
Anyway, if you don’t see a need for tools like nostr you don’t need them.
I’m simply always away. It’s less misleading than being randomly away because I do actual work and am not glued to the computer.
