Very cool. Any way to do this easily on WordPress (for a quasi-technical guy)?
If your website requires login, consider adding login with nostr.
Demo: 
NIP-97: Login with Nostr: https://github.com/nostr-protocol/nips/blob/login/97.md

Not yet, but I made a plug-in a while ago to use your WordPress as a media host:

Should not be that difficult to change it and also allow all you WordPress users to login with nostr.
I might give it a try but I'm working on some other things first.
