  Actually, this is what qualifies as a "wicked problem". Until pgp 1.0
came along, there was no way to know how people would =actually= use a
public-key system. (Sure, there were lots of theories, and a few
academic experiments, but those don't count as RL.)

  Phil tried to anticipate the kinds of errors that would be made by
people unaccustomed to thinking in terms of attacks and threat models.
Face it, the average.net.person is not into game theory. Phil was under
severe time pressure to get a workable public key system out the door
before the government slammed it shut in his face.

  Now that we have had an opportunity to observe people using the
system, we can identify nuances that could never have been debugged on
the test bench. We can explain to people the various paradigms for
viewing keys, and the importance of being able to trust the "identity"
of an anon.id, which seems oxymoronic on the face of it.


  Some kind of explanation by analogy seems in order: We all know of
movie stars who changed their names for Show Biz, or authors who wrote
under pseudonyms. Take Mark Twain for example. A person who had read a
Twain book, or had friends (his own WOT) tell him how good/bad Twain
books were, would develop his opinion of the man's work. His ultimate
decision to (not) buy a particular Twain book has nothing to do with
the True Name of Mr. Clemens.

  Where it =does= come into play is in the realm of law. Had Twain
libelled a person, the means to identify the Man behind the Mask would
be integral to executing the judgement of the court. And even then, if
there were sufficient continuing royalties that could be attatched to
satisfy the judgement, it would only be necessary to know the True Name
of the publisher.

  So we must be very careful of what it is that we are certifying when
we sign something. This is what needs to be addressed in future versions
of PGP.
