I find any sort of markdown notation a distraction. It is, once again, confusing CONTENT with LAYOUT.
If we're talking about the same Markdown, I find your assertion of its nature to be false. Markdown and its derivatives serve to enhance your content, not add new features to it. Content itself is important, but being able mark the most important ideas as well as present data that is otherwise unreadable - say, tables - is no less so; sometimes it even is your content.
