There’s a working proof of concept: open my desktop app, Pretty Good Apps (GitHub.com/wds4/pretty-good), then go to Curated Lists. It will allow your Grapevine to curate a list. Any list. You give the list a name, and your WoT decides what items belong on the list and what items should be removed from the list. But it’s buggy, may crash on you, and needs redesign, which is why nostr:npub1p2uwv7qme2u92y2qcpqqvafhkkqsxfrrnz8m79lm60v4005s7vuqnexr0s is rebuilding it as a web app. In the meantime, you can either wrestle with my app or read an overview with screenshots:
