No such reason. I'm willing to try out AsciiDoc.
I mean I did not try AsciiDoc until now because there are so many choices of input formats and the ones I've tried so far have been disappointing one way or the other.
I talked about Org-mode rendering broken in edge cases. Same with Latex too. I see Pandoc has first-class support for its own Pandoc Markdown format. But the support for all other input formats seem patchy.
If you think Pandoc has good support for AsciiDoc without any edge case issues, I'll be most certainly trying it out.
