Poking around with AsciiDoc again. We think it hits a sweet spot somewhere between Markdown and LaTex. It definitely enables decent quality output in a ton of formats. Pretty sure it makes sense in Alfresco Share context. In fact, we have been using it in Share to write technical documentation for a while (Inspired by Loftux Manual Manager). We feel it should be treated somewhat similar to HTML – w/o OpenOffice preview rendering ?.

AsciiDoc preview is working.
