Love it! Thanks for using no.str.cr. Glad I added client & server caching to this yesterday :).

do you think you will eventually use jack@block.xyz?

could have used twitter_handle@nostr.directory; at least that ties with your Twitter account identity which you already established.

pretty sure they enabled nip-05 already on nostr.directory so your tag should be there: https://nostr.directory/.well-known/nostr.json?name=jack
