"People write harsher evaluations of colleagues in e-mail [and] co-operate less in
group work by e-mail than face-to-face... somehow... rules of social behavior don't seem to apply as tightly when we're sitting in front of
a computer... may be [because] a computer feels like machine, not a human being... or it may be
that a generation raised on informal chit-chat by e-mail has trouble adapting to the stricter world
of business.Tom Spears - The Ottawa Citizen
