The text file looks great, but reading this just makes me think of the XKCD standards comic. Markdown has very few issues, and the remaining ones are so nitpicky that the downsides of having an additional standard are larger than the benefits.

On the other hand, I am always happy to see progress in the LaTeX alternatives world. That typesetting language has become comically overgrown and I think it's turing complete at this point.

> Markdown has very few issues

Markdown's issue is that it isn't a standard, and many "standard" Markdown implementation default to rending HTML tags without any validation.
