I firmly believe that people do not actually want to have technological precision; they want their technology to be able to permit a certain level of deception. Perhaps you’ve been known to say “My spam filter must’ve eaten it” or “I’m going under a bridge so i might lose you” even though you know that these are (white) lies.
In For Liars and Loafers, Cellphones Offer an Alibi, a few mobile phone users have taken this to a new level. They’ve developed a network of people who aid each other in developing and maintaining deception via mobiles.
