It's bad news for Facebook - and then it's not. Only a few days ago, a new study by Pew Research Center found evidence of an increasing "Facebook exodus" among young people as well as growing disenchantment with the leading social media platform among older users. According to Pew, 42 per cent of those surveyed in the US had taken a break from Facebook for "several weeks or more" in the last year. A quarter of respondents even said they had deleted Facebook's mobile app from their smartphones.
