Imagine spidering twitter for phrases of the type "x is a type of y" in order to form a database of real world objects in an inheritance hierarchy. Now imagine when you have these objects, finding out what these objects do by looking at verbs that occur around them. Boom. You have objects, and you have the methods you need to write. Now you just need someone to write the code! The methods writing could become a sort of captcha exercise.
