Fresh from the clogged tubes of teh intarwubs…
"One of the things I realized in the course of writing [Down and Out in the Magic Kingdom], and that I think a lot of people miss when they read the book, is that Whuffie has one of the fundamental problems that accrues to money or property, which is that the more you have the easier it is to get more. That’s a pretty a pretty enormous gap in the Utopian character of Whuffie. A properly Utopian system is one in which you have something that’s a lot like merit, not like circumstance—where people are rewarded based on how great they are, not based how great they used to be. And I think Whuffie is primarily one of those systems that rewards you for having gotten lucky or doing something good some time ago, and then continues to reward you for that forever at the expense of other people.<br />
I think Whuffie would follow a power-law distribution, just like in-bound links to blogs, for exactly the same reason."
