I've got two spoof accounts on Facebook, one for work - we're an agency selling Social Media Marketing among other things,so it's more or less expected of me - and one I established roughly 7 years ago when i started social dancing and constantly meeting people who asked me if I was on Facebook. I looked at Twitter a few months after it came out, thought "wtf?" after 3 minutes and have used it since maybe 4 times or so. No inroads at all with instagram, whatscrap and other data hogs.
Long story short, even though I'm your Type A 80ies computerkid who has never had less than 5 email accounts in the last 2 decades and who was on Fidonet back in the day posting every day, I see a significant difference between me and many many other people. Today *I* am the one who's more away from electronic media than the average - a thing quite unthinkable back in the 90ies. Even though I haven't changed my habits that much.
Facebook I consider particularly evil, as it is a funnel of constant superficial vanity-induced anti-social behaviour that, as far as I can tell, has a significant impact on the general social skills of people growing up with it. Facebook here being a synonym for anything "social" media these days. A fascinating look into someone from this social media native generation is Essena O'Neills account on why she quit her life as an instagram "professional". Yes, you can shake your head in disbelief about the naivity and the obviousness of what she finally realised, but don't forget: these are people who grew up with this - they never knew anyhting else - which makes her account ever more honest, poignant and impressive.
I see the signs left, right and center: Social media has a significant negative impact on the general publics mental health. To put it in other words: FB is not a social network, it's basically a global mental illness.
My 2 cents.
