The use of social media at work is an issue. I’ve had pilots log on during ground operations
Similar reports in recent CHIRP* Cabin Crew Feedback. Checking social media strapped in during taxi etc.
From a safety perspective, and bearing in mind that a number of 'instagrammers' are effectively running a business on the side - 'sponsored' eyewear, watches, jewellery, corporate lanyards, etc. as well as promoting themselves as members of the '#lookatme' generation, the opportunity to take the perfect selfie or capture just the right light for a shot of the throttle quadrant or HDG SEL knob should not be understated and may not necessarily coincide with the safe and expedient operation of the aircraft at that moment. Seriously, though, it's a distraction and unnecessary in my opinion but then I'm getting on a bit.
