This article by David Murray sums up one of my keenest fears when it comes to the online world: the rapidity with which a stupid remark can become a life-altering mistake. Nobel prize-winning scientist Sir Timothy Hunt said something about 'girls' in laboratories at a conference. Social media went wild. As a result, he was forced to resign his position at University College London, the Royal Society and a number of other roles of distinction. In short, one little quip ended his career.
There seems to be no moderation to the online world. It's AWESOME or it's UNFORGIVABLE. Nothing in between.
