Facebook is great for catching up with old friends or friends over seas.  Its also good to find out when people are not home or on holidays so you can go rob them..  My wife set up mine i log on once in a blue moon and the crap you get bombarded with gives me the shits so i log off again.

     Im forever getting texts from people asking what im doing in certain place to find out that the wife has (Not sure what its called) told everyone we are at the movies or some shit like that.   Cant go anywhere without the world knowing.

And the answer to your question your not missing anything facebook just sucks
