assignment of UIDs

[Gregory Dudek]

--
   Aside from the practical problems with numeric logins, there is
the human factor.  Numeric logins are UGLY!  Among the drawbacks 
are the fact that they are hard to remember, and impersonal.  I
was hoping that we are slowly moving away from the days when all our
machine readable identifiers had to be numeric and we had to type
in code in binary.
  Granted, using alphabetic IDs leaves the problem of coming
up with unique ones, but at worst, you could select them (or let
users select them) from a dictionary of available words.

P.S.  Having social insurance numbers for logins sounds consistent
with having all your executables numbered prog0001 through prog9999
and error messages like "Abort: I78551".
