I haven’t read the NIP for implementation details, however this is a much nicer way to support moderated and curated content for Nostr. Opt-in, easy to follow competing/alternative methods (humans, AI, statistics, topic enthusiast, etc), it focuses on its own content and not hiding/suppressing other content, can be primarily hosted by specific private or community relays, etc. and when we get local client keyword/hashtag filtering, you can personalise it even more.

You can build a custom feed admin view that makes it easy to repost existing Nostr events or post new ones. You could even accept proposals for content to get added. You can have multiple curators or just one. You can enforce rules, like required hashtags or content warning on every post. You can suggest accounts to follow or click to follow all when someone joins your community - perhaps similar to discord chat channels - but post focused. nostr:note160wnuh522ufea564e02p9699k4xzl2gvgzjfwrcz63ygfm36e3msj4eldq
