computer trickery has become mainstream as the not-super-tech savvy people seek ways of coping with a 24x7 work culture and the increasing inability of people to dodge uncomfortable questions in an era of "always-on" broadband, mobile phone and instant messaging connections.
It sort of reminds me of a conversation I had with one of my friends concerning his blackberry. I guess he doesn't like his emails to automatically say they were sent via blackberry, because then correspondents will know when he is or is not in his office. He would rather them think he's in his office at all times.
