Nice idea. Could this principle apply to TRIP? Could you allow users to decide if a result is good or bad? Could they vote ‘Digg’ style to say if that result was good or not? A ‘thumbs down’ means that result scores less well next time, a ‘thumbs up’ scores higher and no score means the same score next time.
I’ve mocked up what a ‘TRIP meets Digg’ might look like.
