It's ironic, really. Computer networks bring people together who'd otherwise
never meet. But the impersonality of the medium changes that meeting to
something less -- well, less personal. Humans exchanging email often behave
the way some people behind the wheel of a car do: They curse at other drivers,
make obscene gestures, and generally behave like savages. Most of them
would never act that way at work or at home. But the interposition of the
machine seems to make it acceptable.
