Re: A plea for AsciiDoc i.s.o. Markdown
All the features of actual Markdown, paraphrased from the original doc: Headers, Blockquotes, Lists, inline and Block Code (w/o syntax highlighting, references, etc.), Horizontal Rules, Links, (two kinds of) Emphasis, Images (w/o captions).
For anything else – and I suspect that in journalism you'd at least need stuff like tables, the occasional footnote, image caption, section link, etc. – you have to use some extension, or give up and write HTML.
So, to completely butcher that analogy: instead of a "sledgehammer", you now have a feather, with a set of pliers, a center punch, and a chisel glued to it, to break those roasted peanuts.
That's the advantage of Asciidoc in this context: instead of a set of pidgins, it offers a single, consistent syntax and semantics. All of this is also an enabler for some definitive documentation – and being able to look up 99% of general-usage features on a single reference page is quite a time-saver.
