I have not read anyone else's reply, but here is my take on all this. I only read the PMs I get there and some of my alerted things. That is it. I do not read my timeline. I rarely reply to anything or share anything. This is how I deal with FB. I basically have taken a back seat attitude concerning them.
There was a point when I found myself spending about 2 hours a day on there! I said to myself, NO MORE OF THIS! I DON'T HAVE TIME FOR THIS. So I unfriended a bunch of folks. Basically I unfriended everyone who lived in places that I no longer lived in, with the exception of family members I wanted to stay in touch with. I unfriended about half the people I was friends with, actually.
Now I only go there about once a week. That is all I am in the mood for concerning FB. Any more than that, and I start to feel burdened or put upon.
