Social Media and its power

I watched the Social Media Revolution 2 (Refresh) video... on how world communication has changed due to social media.  I pretty much grew up with it, so I do get it, but it seems that it is always capable of more than even I can imagine... the sheer extent of these statistics blows even my mind.  It has power, which can be used for good or evil, but overall the good outweighs the bad.  Anyone who underestimates it is a fool, I bet it'll go on to do things we haven't even thought of yet.  In our ever-faster changing world it will evolve, but the concept will do very well for a long long time.  We are social creatures.  It was made for us.
