Typewriter completely removes the “Visual Editor” feature in WordPress and replaces it 
with a simple Markdown editor so that you can join sites like StackOverflow and Github in writing in the 
simple and growingly popular <a href="http://daringfireball.net/projects/markdown" rel="nofollow ugc">Markdown format</a>.
For the more technical among you, Typewriter removes the TinyMCE editor and defaults to a Markdown specific “Text” editor 
and parses the output using MarkdownExtra.
