This classification system seems to me to be too slanted toward computer
professions. I say that even though my job title is "Computer Programmer
Analyst"; while the main participants in groups like net.unix or net.micro
would be well-served by such an emphasis, it has no bearing in groups
without a professional orientation (net.consumers, net.rec, etc.) and
is inappropriate in groups aimed at other professions (net.bio, net.physics,
etc.).
Perhaps something as sinmple as a cumulative total of the years of a
person's USENET experience (or even just "net experience" -- I was active
on the ARPANET for 6-7 years before I had USENET access), and the list
of keywords, would serve the desired function?
It's probably highly unlikely that any but a few would end up using this
in any case, though.
