For many years some of us have argued strongly for "reputation" as a core concept. Someone, perhaps even one of our own, even coined the phrase "reputation capital."

Absolutely. I may trust you, but I might not trust (or even know) your best friend.
Reputation is an easily understandable concept which explains a lot about how imperfect protocols in the real world nevertheless "work." I won't go into what reputation is, even as defined by folks like us.
It may be 'easily understood', but it's also easily misunderstood (by many).
In what way?
But there are many aspects of reputation which lead to problems:
Reputation itself is a problem. Past behaviour (toward another) is not a reasonable predictor of future behavior (toward myself).
Yup, apparently there have been recent cases of high-rep sellers on ebay who when ready to give up the ebay game put up auctions for high priced items that they never deliver, effectively stealing the money. It would be interesting to figure out an effective way to prevent this. Now ebay and things such as paypal, Visa/Master Card have measures against this type of fraud, but they usually just eat the losses of the bidder. ----------------------Kaos-Keraunos-Kybernetos--------------------------- + ^ + :Surveillance cameras|Passwords are like underwear.
