The idea of hub exists not only in the social network; moreover, it can be considered in an online space. Even though it is suggested by Barabasi that hub is nautrally formed, the question of “can we create hub?” emerged in my mind.

As I previously suggested, I have noticed the “key person” or the connector in a social context where a person that connects different clusters together. To think of the idea of hub in a cyberspace context, we can consider yahoo as a hub because there are so many page pointed to yahoo. If we were to create a person as a connector in a society, we would have to push the person to a very social level. (The example of social climbers who try to meet all different people all the time can be considered a creation of …

Because of the nature of our interconnectivity in a complex network, if one of us fails all of us fails. The example of a power network breaking down causing multiple power outage in several state is a perfect example. “When a network acts as a transportation system, a local failure shifts loads or responsibilities to other nodes.” (Barabasi, 2001) This will cause the whole system to fail because the neighbors cannot afford the load. It’s like a chain-effect that won’t stop. Cascading failure is the price to pay for topological robustness. If the hub is attacked, all the links linked to the hub will fail.

While most of the systems in nature follows a bell curve, which is a distribution of that’s similar to the peaked distribution characterizing random networks. By looking at the society, we can find out that the most of the people fall in a range of height. The height of people are average out throughout the general population. (i.e. generally full-grown males fall into the range of 5-7 feet tall.) However, there are occasion in the normal bell curve distribution in different system. Instead of following bell curve, systems follow power law distribution.
