I can totally understand those people who are passionate about the simplicities of Dropbox and Markdown, although I’m happy with Tumblr which is the best BSP so far and am not intended to replace it.
If you’re one of those people, good for you by the way, I’m telling you that now you can start a blog with them by using either Calepin or scriptogr.am.
Basically, it is a simple online tool that converts static Markdown text files located in your Dropbox, into a beautiful web log. (Quoted from scriptogr.am)
If you still don’t own a Dropbox account, oh you really should.
