I've been off Facebook for about a year now as well... Lets see the effects have been, a lot less options for dating, lost communication with a ton of various car parts companies and tuners (I was into a lot of car hobbies for a while), and overall I feel more alone then I did when I was on Facebook.
But this is an honest way to live, I used to just sit there and scroll through other peoples lives peering through them as if I was somehow a part of whatever they were doing. It was a fake reality.
