I am now flying on WordPress 3.2, which was a fairly painless upgrade. One of the new features is a full-screen editing mode for creating posts. A nice idea, further enhanced by the way even the basic interface elements are hidden until I move the mouse, just leaving me with a plain white screen on which to type my words.
I have heard of writing software with similar distraction minimisation strategies in the past but this is the first time I have tried it and I am finding it rather appealing.
