Or for example it would be cool to see a news servers fully served from the nostr relay swarm. E.g. why can't this page https://www.economist.com/ be served from nostr? It's daily updated repository of news and articles. Nostr static page could do the same.

It's a separate topic, but it would also be really cool if it's all based on markdown, so the clients can compete on who provides the best experience.
