As close to mind-reading as I have seen, I used presdo the other day to arrange for a meeting and it worked pretty slick. I like the streamlined interface where you just type in what you want to do in words and it helps you fill in the blanks.

Furthermore, I like how the developer (a co-founder of LinkedIn) bootstrapped the development on his own money. I am feeling an affinity with enterpreneurs of this type currently and hope it is wildly successful.
