An online game that gets

An online game that gets smarter the more you play it: Guess The Dictator/Sit-Com Character. Think of a person (any old dictator or sitcom character will do, apparently), and you will be asked yes-no questions, twenty questions style, until the computer guesses who you’re thinking of. If it’s wrong, you add a new question to the database so it’ll win next time. It’s an intriguing concept that sadly doesn’t turn out to be that much fun.
