It has been almost a year already since I decided to stop using facebook. Tell you what, It feels great not seeing all these showbiz personalities, the faces of these stupid politicians, the drama etc...Would you quit facebook?, just try it and I assure you of one thing and that's "Reality".
I personally enjoy FB.
Thanks to FB I can find my ''old'' friends from school or home city, 20-30 years ago see how they live, their family photos

Of course I don't like spamming, ads etc.
I really love Facebook it's the easiest way to connect to Our love ones and Friend which are very far away from us around the world. I don't think so that quitting in Facebook is a good idea.
