I’m sure that this wouldn’t be to popular for the diehard mathematicians, as they all swear by using LaTeX, which can be converted to HTML by MathJax.

That’s probably similar to that there will always be people that swear by using HTML even if they have the option to use Markdown. But for people that just sometimes want to use a little bit of mathematics in their markdown chat/discussion/article/blogpost etc. having a mathematics extension to markdown could be quite useful.

I’m thinking about things like:

Probably not a priority at this moment, but I just want to drop the idea. Peter Jipsen wrote such a kind of markdown alternative to LaTeX already 10 years ago, for the people interested: http://www1.chapman.edu/~jipsen/mathml/asciimathsyntax.html

But I think this is already too feature rich. I would rather have only the very basic mathematics in such a markdown extension, and leave the heavy work to mathjax.
