Here is one of my problems with it. Social media mostly happens real time. Because of that it unnecessarily injects drama into your life. I don't use any of the main social media services. But, my wife and kids do. It is not unusual for something to blow up online within their peer groups. So my wife and kids start hyperventilating about what happened and looking for solutions and then something happens and the issue gets resolved pretty much on its own.
So, I manage to get through the whole day without drama. And when I eventually hear about what happened, it is all resolved and everything is back to normal. They on the other hand have spent their day caught up in this non-crisis and wasted all kinds of time, energy and emotion on it.
There is definitely such thing as being too available. Many of the social media services make everything too available.
