I went through my FB list and "unfriended" over 150 people. Still have another wave to do but just couldn't handle much more at that point. I think streamlining our friends list is good.
It gets the braggers out. It gets those who may thrive on our disappointments out.
I am very handy with the unfriend button now and don't think twice about using it.
I still cruise FB because my five teens and my entire family is on there but I now am in control of who is putting what in front of my face.
I am also no longer allowing others to dictate what I post on there. If I want to post that I am having a bad day, I will. That's what friends are supposed to be for is support and those who do not want to support can use their own little unfriend button and just delete me if they want to!
