I stopped connecting to Facebook (the only social networking account I had) last year. I don't remember exactly when but it feels like it was ages ago.
At first, I questioned whether I would 'survive' not seeing updates from my family (who live on another continent) and friends. It was fun to browse through their photos but this activity would usually last hours. During these hours, there is so much that can be accomplished. And, I have lots on my to-do list that I would postpone when facebooking: reading books, studying, spending time outdoors, improving my baking skills, blogging and more...
