The job is done here @inboundinken and it is a great article, but im pretty sure that such thing as "steemit - facebook compete" is possible for a very short frame of time, because facebook does not allows their users to monetize their content so well- and we have it over here. Steemit getting bigger than facebook is just a matter of time ( if nothing unexpected is going to happen ) and thus it will win with other social-media giants.
But it is only my opinion :) feel free to argue with it haha ;)
