> I feel like Jeff Atwood and his friends abandoned the Commonmark project that tried to create a universal specification of Markdown. Even if they did, I don't think that Github, Stackoverflow, Reddit and other major Markdown users would ever convert.
Came here to say that. Also Discourse just moved to a CommonMark compliant markdown parser this release, so between GitHub and Discourse the user base is already huge.
The CommonMark project has not been abandoned; the CommonMark C parser was implemented on GitHub earlier this year and is used to render Markdown across all repositories: https://githubengineering.com/a-formal-spec-for-github-markd...
