The hidden influence of social networks

TED
Nicholas Christakis: The hidden influence of social networks
Summary
We're embedded in the social networks. It's very complex and elaborate though great, beautiful and ubiquitous.
Our current social networks are created by this moment connection. It might be fundamentally encoded in our genes. It'll be tied to emotion, behavior and norm, of course, people around us influence us.
However, not only people around more wide areas and the collective or groups but also its structure influence our social networks.
The structure of connection is like the connection of the carbon atoms. When it's arranged in one particular way, it becomes graphite which is soft and dark. However, when it's connected with a different way, it becomes a diamond which is clear and hard. The carbon atoms don't have properties of softness, hardness, darkness and clearness. Those properties reside and arise in the interconnections between the carbon atoms.
The similar things happen to our social networks also. If our interconnections and its structure change new properties will arise in our social networks.
It must be more valuable. How wonderful if our social networks are like diamond which has good interconnections.
