I really like AsciiDoc and would encourage anyone to give it a try, especially for things like software documentation (in all forms). I very much despise the trend to write sharepoint or wiki/Confluence pages as a means for software documentation. I want my documentation to reside next to my source code, not at some obscure corporate URL. The problem is simply that github, gitlab, and friends adopted Markdown and so…
It wouldn't be so bad if Confluence/whatever could just render the Asciidoc from the source repository. But they are generally closed systems. There's no way in or out of Confluence without significant headaches.
