What I am is what I am you what you are or what?

My  niece mentioned a 20-questions-like web page The Akinator, the Web Genius that can be fun to play. It took the thing more than the original guesses to come up with what I was thinking of both times I played, but when I continued, it guessed correctly. And without really a lot of information to go on. I think I'll try again with Edina Monsoon.. Yes, it guessed her with no problem.
