Articles about the death of social media appear frequently these days. They have a bit of catching up to do though as articles about the death of blogging have been being written for at least the thirteen years I've been involved. I guess pundits have to write about something and they are either on the rise or fall of the wave they themselves create.
But these waves are just noise on the greater wave which is the impact of connected thinking and minimal cost distribution of ideas which the internet is enabling. That isn't going away. Fears about privacy may make us retire into echo chambers for a while, and the commercial machine will continue to trundle on to the next technology innovation, but it would take a concerted effort to unlearn what we now know - that we have the potential to find our voice and use it.
