Here is why both #nostr and #mastodon need #markdown support. Here I am trying to show code snippets without but they get interpreted very differently on different clients.

(If you can add mathjax support for the mathsotodon.xyz folks)

This note nostr:note13f89879p6g49995w4dafsrf5w93gsxmn5m2rnm2arlvljm60lhvsc33ckp

shows on #primal like this:

https://void.cat/d/3DQd4z4M7SZx1kMPCurau4.webp

and on #mastodon like this

and again differently on other #nostr clients.

In the Primal UI the URLs for the RDF get interpreted as URLs and some preview is shown, but that is not the case with other viewers.
