Isn't markdown more standard and what Nostr already uses?
Discussion
Yes, for normal articles (30023/24). And all long-form accept the simplest markdown, like headers and bullet lists and etc. But wikis (30818) and modular articles (30040/41) will also support Asciidoc.
Asciidoc allows us to do real publishing, and to include things like custom tables, img resizing, UML (including PlantUML), Latex, AsciiMath, stylesheets for magazine or website publishing, scientific journals, etc.
