"I've become convinced that understanding how networks work is one of the most important literacies of the 21st century."
That's how Howard Rheinhold introduces this "mini-course" on networking and social networks.
Citing works and references to human networks of centuries past through to virtual communities and smart mobs and how to self-organize, Rheingold packs a bevy of valuable history into this video. It ends with a discussion of copyright law and net neutrality as ethical conflicts of individual freedom vs. institutional control.
