I did this a couple of years ago, when I was having keyboard issues with my old laptop. The "A" key only worked about 20% of the time, and I was really tired of having to go back and edit every post (and just sitting there slapping the "A" until it worked), so I decided to leave a post unedited. I am perhaps a teeny bit obsessive about spelling and grammar (among other things), so it nearly broke me to hit send, but hit it I did, and the post is there for all to see: http://kissmyfrog.wordpress.com/2010/04/23/venting-my-inner-dork-with-only-twenty-five-letters/
