Markdown is holding you back (opens in new tab)

The main point of Markdown is that it has a very important feature that other languages don't have: it's supported in a lot of places. Most of the alternatives mentioned in this thread or in the article are things that require custom tools, that can't be used in most of the places that currently do support markdown. It's common in a lot of places. Even Google Docs has a well hidden feature that allows you to paste markdown.
