Romero’s article has a lot of good points for the nostr ecosystem to think about: https://danromero.org/rss-plus.html I like the RSS+ idea. Did you know that all Substacks have an RSS feed (just add /feed to the end: yournewsletter.substack.com/feed)? If nostr clients would parse RSS feed natively you could read RSS feeds such as Substack newsletters within your browser. It would allow the integration of zapping, sharing and other nostr features around the “RSS notes”. Why try to convince existing newsletter writers to post on long-form nostr if the existing feed can be used as a starting point? @Fabian RSS-parsed posts as a special feed tab on Nostur?
I haven't read the whole article because skimming it and seeing crypto or blockchain as solutions triggered a close tab reflex for me. But your comment about nostr features around RSS notes is interesting, and I would generalize it to nostr features or conversations around URLs. NIP-84 (Highlights) sort of does this but it has the emphasis more on a partial blurb that someone finds interesting. I'd like to see something where the article or URL is the "root", and then your client would show something like "Petri & 2 others have started a conversation around this article".
Composability is good feature. Lots of existing use cases that are silos at this point. E.g. imdb for movies, goodreads for books etc. Some are standardised and probably all of them have some sort of OG url source around which things can be composed of. RSS is good also for podcasts and other decantralised web purposes where it was originally created for but got sidetracked by web 2.0 centralisation. In Romero’s article you can replace the blockchain with Nostr notes. And his solution was to use blockchain (with Farcaster which is a decent implementation) but the premise is valid. How to build a new social network and to gain traction with existing services, protocols and technologies.
