Etherpad is an online text editor that saves every keystroke — so far, so good. But it also allows you to play them back, giving you a birds-eye view of how a document came to be. This is how Paul Graham wrote Startups in 13 Sentences. Watching someone else write is interesting enough, but I can imagine playing back the evolution of one of your own pieces of writing is absolutely mesmerizing. Consider all it could tell you about how you write: it could potentially improve your writing considerably by making you aware of how you write, or else it could cripple you by showing you how much crap you turn out for every word of decent prose.
