The way it is implemented (with the card back/front style) suggests that it is shuffled in with the rest of the blue rules and used in place of regular card if you draw it when creating a game. (Or you can select it from the beginning as such). But that's just what I remember off the top of my head. There may be something RAW about it.
There is something in the package that states that you draw another communications card and use both - the Social Media is a common power that anyone can use.
