Facebook is pretty easy. For the first time friendships don't have to be lost when someone moves away, or changes interests in a forum.
Just put a pic as a status and everyone you have as a friend will see it whenever they check their newsfeed.
Pretty crazy but I believe if everyone was required to have a Facebook by law, humanity would be united, peace on Earth! Of course governments surely wouldn't like that, hence the evil fake smile when they see Facebook and the like doing so well.
