Facebook is a time suck. It is a good way to keep up with family but you really have to limit your friends list. I am all for being friendly but NO ONE has hundreds of friends and no one needs to know that you are at home bored again on a Friday night (for heaven's sake call someone). There are also many things on Facebook that can sap your time and empty your wallet such as Farmville. Make up your own mind but I have an FB page but rarely use it.
