IMHO nostr should adopt mp3url (.m3u) playlists, which would allow users to share images, video and audio over relays.
In theory clients could then display slideshow-like posts, in feeds.
The original "Semantic Inbox" was desgined to be like your email inbox, but with more features, because it was over HTTP. The first protocol to use it was Solid. Then came ActivityPub, which sends JSON objects to DNS based inboxes. With did-nostr we can complete the project, by giving every npub a private inbox. Then you can send various kinds of chat messages there. Below are the privacy-trade offs. The same system can be used to send payments or bearer cash. It will be usable by humans and agents. Finally the semantic inbox we deserve.
Nice to see more people digging into this. Bitcoin has never guaranteed censorship resistance, at least, not 100%. Miners always pick what to include, usually based on fees, but also on what they think matters. If spam is deprioritized, it takes longer or costs more to get through, making room for the high value tx, that end up paying miners more (long-term). That makes bitcoin more sustainable in the long-run.
