This is actually taken a bit out of context in you watch the full interview. This response was to the question of what experiences from Digg are you taking with you to your next startup and what are you going to do differently.
You could get two other friends and be rock, paper, scissors. Then go around battling each other with character driven dialog. For example, if you're rock and you fight paper and lose, you would scream, "Why does this keep happening?! What does he have that I don't have?!?!"
Regardless of thinking speed, the more you know, the better you think. You are able to analyze a given situation or problem more effectively because you can draw on past experience or knowledge and make a more informed decision. I would happily take an 'experienced' brain over a young on that is faster (if thats even true, which i dont really believe...).
