Realistically everything my several hundred friends have to share with me takes maybe 5 minutes a day to go through (close friends of course would call about things that are too personal for facebook so this is about things more distance friends would care about) . There is a lot more money in the handful of people who are scrolling through, finding, and sharing various memes and news that will make you angry (though this is fun if you - like most people - have friends on both the right and the left doing this and so you can see the bias each side is taking) than there is in friends sharing their life which is not lived on facebook (unless your a physically disabled and so you can only live vicariously through others)
