When I am working, my job often involves hours of sitting around waiting. Or long journeys by train. My ipad has improved the quality of my life immeasurably. In every hour I spend waiting I will probably spend at least 15 minutes on Facebook, scrolling through my news feed. I have a mixture of friends and organisations so there is always something interesting to read, or someone has posted some photos which I can look at IF I WANT TO.
It is unusual for me not to check Facebook at least once a day, every day. Same with twitter, mumsnet etc. Probably about an hour of my day every day. I almost always find something of interest to me, either professionally or personally. It has revolutionised the way in which I am able to access information and share it. As far as I am concerned, it is an entirely positive thing - because I use it in a positive way.
I don't troll, insult people, or sit there muttering and rocking because so and so has had the temerity to post some holiday snaps. The bitch.
I still manage to hold down a job, raise a child and keep a relatively clean and tidy house. I manage to see friends in real life, read books, go out on adventures.
An interest in and use of social media is entirely compatible with being a well rounded person who enjoys life generally. If you really find that hard to understand, again, not my problem.
