TED Talks often pretty great. This one had my jaw dropped right down to the floor.
Just over half of the talk is on how infants learn to speak, then at the 11:48 mark presenter Deb Roy applies his research to social connectivity. It is worth watching.
He presented 3-D maps of the social universe. Media sources on one plane and viewers/commenters on another, with a web of connections between the two planes and a web of connections between the viewers/commenters themselves. It was as if someone made the Internet into a model city.
MUCH to infer from this. But all I'm going to say for now is that this is very important. This is world-is-round stuff.
