Brad, I would not included a Hayek --> Galbraith link on 
an economics family tree, simply due to the fact of information 
overload.  This link does not seem significance enough to 
include.  And certainly a teacher-seminar participant link of 
this sort establishes only that -- a seminar leader-participant 
relationship.  I claimed no more.  A family tree establishes 
an intellectual link, but it does not say what the precise impact 
of the link might have been.  In some cases this will be clear 
enough to warrant a Web page link, certainly the Hayek-Hurwicz link 
as teacher-student on the knowlege problem is a solid link with 
clearly evident and easily characterized content, and clear documentary 
support behind us -- Hurwicz tells us about his dept to Hayek. 
The Galbraith thing was simply to demonstrate that what you think 
you may know about who was associated with whom many in fact not be 
the case.  A Web page link can help open our eyes, perhaps just a 
bit, to some thought provoking and thought changing personal associations 
and intellectual associations.
