Back when SubEthaEdit was new, I was a writer on a comedy show. Many afternoons, our team of 4 to 6 writers would get into something like a competitive I-can-finish-you-joke-before-you-do edit war. I don't remember ever again being paid for having that much fun.
But that only worked before SubEthaEdit worked absolutely flawlessly with anything we threw at it. You'd have two people editing the same word, yet it never occurred to anybody that we weren't actually all playing with the same piece of clay.
(Moral of the story: "nobody would ever want to that" is a self-fulfilling prophecy)
