If you're looking for a distraction-free writing tool, I've been building and using a minimal blogging platform called Tinylogger[1]. My focus is on a totally clean interface (everything goes away while you write [2]), and I recently shipped a no-judgement mode [3] that focuses you only on the line you're writing, fading everything else out - perfect for first drafts and morning pages. I've been blogging a lot more this way.
