Awesome! I think I can create a tool for adding "edge names" -- names given by a friend to a friend-of-a-friend. Then we'll have a full petname system on nostr:

- A petname is the name you manually give to someone

- A proposed name is one given in a profile -- clients can display them with an indicator that they might be an imposter (unless/until you confirm them)

- An edge name is supplied for someone you haven't picked a petname for yet, by checking if any of the people you follow have given that person a petname

Can this system prove better than DNS? I dunno but I'd like to find out!
