I have a love/hate relationship with facebook. In the main it seems to me to be a platform for narcissism and I keep being asked to follow Mark Zuckerberg. But I do like seeing what my friends and family are doing even if they are having a better time than me. i keep it purely social and nothing to do with work. So along comes facebook with a business app to compete with Slack & Yammer to promote internal comms and employee engagement. Neat but do we want fb at work?
