We can't have handles on nostr because of Zooko's triangle. 
Discussion
Best we can do is self-hosted NIP-05 which turns your domain into your handle, which is why the following link leads to my profile:

oke i see now what you mean
i say we rebrand what handle or @ means - both nip05's and npub can fall under it 😗
Sad once I read Zooko I'm just out. I'm sure he has a great triangle. May his groceries never end.
Well somebody should tell Zooko to stop with that triangle so that we can.
