New Form of Social Media

One form of new media that would exist could be an interactive storytelling mechanism which would be truly robust.  Whether based on complicated AI and simulations or based off of aggregated responses of lots of users/players, there would be a scenario created that players would then create events of their own design, rather then the common pre-chosen menu, to create a new situation.  There would then be responses from simulated characters who would advance the story, again within a robust rule set as created by the designers of this new form of media
