I'm reading "It's shaky. Accept that." Fine, consider it accepted.
 
I don't think it is comparable to the market, simply because even the
more nebulous market exchanges (say, consultant-on-call) are much more
clearly defined.

I don't see how there can be such a thing as negative reputation
capital. Wouldn't that mean B believes the opposite of what A says? If
you anti-believed someone in a consistent manner, couldn't they exploit
that?
 
Also, you are speaking only of 1-to-1 reputation-relationships. But that
is inefficient. The mere fact of having to evaluate each person's
reputation yourself is significant work.
 
On the other hand, you could talk about the transmission of reputations.
This seems more in line with what I understood "reputation" to mean, to
include some element of indirect knowledge. But that's mighty easy to
abuse and therefore mighty hard to trust.
 
For instance, when a certain infamously-low-reputation (deservedly so)
individual recently joined the cypherpunk lists, others who had endured
him in the past tried to relay their impressions of him. It proved very
difficult to convey, and they were somewhat attacked for their efforts
and not entirely believed.
 
In other words, he *could not* spend down to 0, despite years of
unflagging effort.

I can't dispute or agree with your mathematical model until we can agree
on more basic issues.

I'll accept your example, but I don't see how the numbers are
meaningful.

Well, how many people did J. Anonymous Gourmand reach, anyways?
 
Now, suppose J. Anonymous Gourmand spams all of Usenet, and millions of
people who have never heard of J. Anonymous Gourmand before read a
plausible but false account of the disgustingness of McDonald's food.
Perhaps the same detailed study, just fake. (Not to intertangle this
with other issues, let's further suppose that Ms. Gourmand sneaks in
underneath spam-watcher's radar, and cleverly appears to be on topic in
every group.)
 
Nothing about her reputation has changed, but surely when her claim is
read by millions it will hurt McDonalds a non-trivial amount.
 
Again, that doesn't mean the reputation was not a factor.

I don't think you are illustrating what you think you are.
 
Consider the American Sociological Association. Wouldn't you say its
reputation is equivalent to the American Heart Association's? Most
people would, I think. And various claims by ASA members have certainly
gotten as much press as anything the AHA has got. But the ASA winks at
severe violations of its Code Of Ethics and lets its members pursue
their Politically Correct agendas at the expense of science. They have
effectively counterfeited a reputation.
 
I've already made the points I wanted to make, so I may not have further
comments.

I'm evolving a hunch that the problems we're seeing with "old fogies"
denouncing the Net, and anonymity, and "smut on the Net," are part of a
larger cultural issue. Namely, the familiar case of an older generation
complaining about the sloth and sin of the younger generations.

(Caveat: I'm 44, so I'm certainly a generation older than many of you, and
am about the same age, give or take a few years, of Dyson, Metcalfe, Kapor,
Denning, and the other Net.Doomsayers. However, 20-25 years ago, when I was
in college, I recall of course similar predictions of disaster. (And as it
turned out, the predictions that promiscuity would lead to a disaster
turned out to be partly correct, viz. AIDS.))

Robert Metcalfe, inventor of Ethernet and founder of 3COM, and how
publisher of "Infoworld" and sailing enthusiast, was interviewed on CNBC a
few minutes ago. He repeated his prediction of an "Internet collapse" in
1996, based on overuse, on bad pricing models, on lack of controls, and on
other concerns.

It could be that the Dennings, Dysons, Kapors, etc. of the world are simply
growing jaded with the Net and are projecting their own ennui in their
comments that the Net may need to be controlled. This may come with age, as
I'm sure the Kapor of 25 years ago would not have wanted President Nixon
and Attorney-General Mitchell telling him what he could read and write.

(In fairness, none of these folks listed have called for censorship. But
all have expressed "concerns" of one sort or another. Not that discussing
concerns is inappropriate--after all, we do it all the time. But I sense in
many of their phrasings of concerns a stereotypical "old fogeyness"
emerging.)

Just a thought. Maybe the solution to the EFF problem is to "not trust
anyone over 30."
