Is there a nip for lists with k tags? I think it’s a great idea and would work great in the app I’m building.
Discussion
Not really, but it was recently added to the Generic Repost here: https://github.com/nostr-protocol/nips/blob/master/18.md
The `k` tag is being discussed in many other event kinds. So, I would say just use it. We can change the lists NIP later.
