For Session 2

       Trolls 'suck', but they're not going away

'Twitter produces drivel, but many lonely people find it indispensable. It allows contact without commitment or judgement. As for using the law to deal with stalking and threats, the police have enough on their plate without prosecuting trolls. Twitter can’t be put back in its box; it will just die a natural death when a new shouty way of communicating comes along. Many have already migrated to Instagram or Snapchat.
All these sites have their dark sides, because they reflect the kind of people we’ve become. Self-obsessed, cynical, restless. Maybe it’s a good time to reread Marshall McLuhan, the man who coined the phrase “the medium is the message” back in 1964. The Canadian philosopher was once very fashionable, but these days most iPhone users have probably never heard of the man who coined the phrase “the global village”, and predicted the World Wide Web. McLuhan was fascinated by the dynamic effects of new technology on society – often in ways we could never predict: more pointless communication and less real conversation. Instant reaction, less reflection.
Andy Warhol said everyone would be famous for 15 minutes – and now everyone can have an self-important opinion. Twitter, like the internet, will never be policed in a meaningful way. If you can’t stand the heat, get out of the kitchen.'
