I think you have raised several substantive issues and would like to see
more discussion on all of them.
I would like to add another: How should the content of Net
messages/newsgroups/forums etc. be monitored, if at all?
Since the Internet culture has strong historical ties to many academic
and government institutions, the issue of free speech and censorship
will definitely come up. What if a member of a politically correct
group is offended by an electronic message? What if the government
presses charges against the offending party?
Mull it over...
