True. 
Now I’m thinking Nostr clients could have achievements like duolingo, reddit or steam does. 
Reward users for completing profile, for engagement, posting, reposting, zapping. 
I think it’s a way that platforms onboard users on different functions. 
I realize that zaps are the trust layer but smth like reddit karma or whatever is trust system on stack overflow might motivate users to engage(provide value) morr
