This TED talk, Listening to Global Voices by Ethan Zuckerman is something of wake-up call. It is very easy for us - especially the digital us - to imagine that a global internet infrastructure means that we are all somehow automatically connected and gaining a broader worldview. Zuckerman illustrates that this is far from the case (we live in "filter bubbles" or worse, in a state of "imaginary cosmopolitanism") and that achieving broader connectedness requires a change in thinking - to break the human tendency to homophily ("birds of a feather flock together"). He sees a special role for people ("DJs") who are bridge builders between different worlds.     

At the level of brand conversations, it is a timely reminder of building broadly based brand communities and the strength of weak ties that we have posted on previously.
