I had not considered this, but it makes sense. I still prefer writing this kind of stuff in iA Writer, as the point is removing distractions and a (to me) nicer editing window.
But it is useful to know. It does carry over all of your formatting, including font and background color. But those are quick to change once pasted into Mail.
I found a very interesting video about this:
Wow - I must admit I never heard of AsciiDoc before but it does sound intriguing
I am pondering if it matters that it is not as widely used as other formats since it can easily output to HTML anyway
Seems like it would have been nice if AsciiDoc had been adopted widely before Markdown took hold
Has anyone tried it? While I have never heard of anyone using it there are quite a few apps which support it which leads me to think there is somewhat of a market out there for it.
I am starting to use it, for technical documentations - as it offers so great ways to handle source code dynamically.
I convert existing Markdown stuff with pandoc to AsciiDoc and continue from there.
For most stuff, i don’t need AsciiDoc and Markdown is simply enough.
But having options and something for the next steps, is simply great 
I can see the benefit being able to include dynamic content
Moreover if Asciidoc viewers/compilers routinely output html that is helpful since ultimately all of my writing needs to be in Word to share with clients - and Word can easily import an HTML document.
It certainly matters to a small company with finite time and resources making development decisions.
