I like Markdown and I used it in all my projects, saas ecomerce and cms, from the beginning (2004).
I'm pro to open standards, interoperability and sensible retrocompatibily.
But nothing is perfect, needs and use cases change over the time; I can see how Markdown standardized the italic / bold / bullet point syntax, that is now used in a lot of contexts even by non techical persons, but images and links never took off, probably for their syntax's complexity. Can we brainstorming about a semplification using Nostr as real use case? I think yes.
