From Stuart Leslie
Jim Giles imagines he is a curmudgeon because he withholds information from Facebook (28 April, p 40). I go further and do without social media. I just see the obsession with them as wholly trivial and time-wasting, and based mostly on a need to conform and not feel left out of something. In many people, use of these media seems to be an uncontrollable addiction and obsession.
