I would like you to share your understanding in response to the following:
a) Why sites like mystarbucksidea.force cannot be counted under social media? Even if such stakeholder engagement platforms are owned by companies that market directly, they can be spun off tomorrow to make them largely independent and broadbase themselves as general purpose social media.
Isn't there too much at stake for big companies to leave social media to few outside players like facebook and google+?
b) If social media continues to be increasingly powerful, it may eclipse or even subsume traditional media (print, broadcast etc.) that is mainstream media today. In such an event, it may no longer be possible to tell social media apart from other media and as a consequence; social media marketing apart from rest of marketing. It'll just be part of integrated marketing like what happened in the case of Integrated Marketing Communications (IMC).
Do you foresee a scenario in which almost all media shall be subsumed under social media?
