How would it work for individuals who write about or cover multiple disciplines. Would they be added to multiple channels?
Yup. I would add nostr:npub1uyz4w2w4rcphk0q5arzkutrecgscxwzajj4dkvh9mjyqjtxslm6qea8632 and nostr:npub1a2cww4kn9wqte4ry70vyfwqyqvpswksna27rtxd8vty6c74era8sdcw83a to the channel on the Fed from a bitcoiner perspective but maybe my WoT would know of some other good sources I’ve never heard of.
Discussion
Yup, no reason not to do that.
Potentially, users could make several alts for different topics. Although that may be more trouble than it’s worth.
Another option would be to curate content at the level of the individual note. That would have its pros and cons. Ultimately, content could be curated using both methods simultaneously: curation of pubkeys and curation of notes.
I’m thinking initial rollout would curate pubkeys though, not notes. Easier for clients to incorporate that way. Just swap out the list of pubkeys in the filter they’re already using for the content fees.
