Social media is fun. It is the way we share stories, stay connected with friends and family, and record our (sometimes ridiculous) lives. But increasingly, it can also be damaging – the way you get yourself fired or the thing that stops you from being hired in the first place.
"There are many ways social media can promote or destroy careers," says Professor Arne Krokan, a social media expert at the Norwegian University of Science and Technology. "It is like water on a porous surface, it is difficult to wipe it away once you've spilled something; it is almost impossible to keep control of content once it is published online.
"This can be good for building a 'personal brand' online, but may affect those who change their behaviour, opinions or political positions over time, and have old or contradictory content retrieved."
