there's nothing worse, in my opinion, than writing a blog post in a wysiwyg web form when you know how to type and all you want to to is just type up a post. c'mon, it's 2011 and editing text in web forms is an execrable experience, one of the least pleasant things to do in a browser. markdown is a snap to learn and it is such a relief to be writing in your favorite text editor, without the copy-paste rigamole.
