for me, Facebook have two benefits, the negative on and the positive one.
The negative one, Facebook now is full of drama, showbiz stuff, nonsense and other things than might ruin your day, BUT come to think of it... it you don't what to see those kind of stuff you can adjust it on what you just like to see. Facebook itself cannot adjust on you.
The positive one, Facebook helps you to communicate with your relatives abroad, or to your old friends. Facebook make your life easier to have contacts to people that you know. There is also things than may lighten your day if you're having gray sky.
It is your choice on what you want to have and what you want to see.
