I just read about this the other day in The Slow Web [1] by Jack Cheng:

"iDoneThis is a part of the slow web movement. After you email us, your calendar is not updated instantaneously. But rest up, and you’ll find an updated calendar when you wake."

I like that it can be used as the opposite of a todo list. Instead of a list telling you what to do, you tell it what you've done.
