How much is an introduction worth to different people for you?

How much would you pay for an introduction from someone to their 10 richest friends? How about their 10 smartest friends? Their 10 best looking friends? Or their 10 wisest friends?

Maybe the value isn't from new introductions alone… What if there was an objective measure of such things as intelligence, looks, and wisdom? How much would you pay to get a rank-ordered list, telling you where all your existing friends and acquaintances rank on those scales? Might you find some surprises that warranted a “re-introduction” to people you already know?
