Facebook is a site founded by this moron.
It is a website used to see what your friends are doing. You can also follow businesses and see what they're planning for the future.
But obviously, that's too good to be true. Not only is your boss interested in what you post (from what I read), but there's also ads, based on your search history. That's right. Facebook stalks you! :D
Too bad my family doesn't love me enough to just email me. :(
