Already in 1906, was an Italian engineer named economist Vilfredo Pareto made a surprising discovery: 80% of the land in Italy was owned by 20% of the population. We studied the patterns of land ownership in a number of other countries and found that the same relationship. It also found that the relationship seems to be the case in other contexts: for example, 20% of pea pods in his garden produced 80% peas

In the 1940s, an American engineer named Joseph Juran observed that 80% of quality problems in industrial systems of mass production seems to come from 20% of causes. Then he came across the work of Pareto and the name of the division 80/20 Pareto Principle in his honor. Thus was born one of the canonical rules of thumb business consulting.

proved that the Pareto principle was really a special case of a more general phenomenon, namely the fact that in many areas of life there is no such thing as a typical or average. This is worrying because we are culturally programmed to think in terms of averages. For example, if you draw a graph of the height distribution of a large number of men or women, you get something that looks like a bell curve, centered on the average height, with very little dwarf and still fewer people who are over 8 feet tall. And he knows this state of things we call "normal distribution".

The problem is that the normal distribution is quite rare in many areas of life. Urban populations, the sizes of earthquakes, lunar craters and solar flares - to take just four examples - not normally distributed. No more than the size of computer files, the frequencies of the words in the books, the number of articles written by scientists, site visits, inbound links on websites, sales of books and records or income people annually.

Guardian online feedback where 20% feedback is provided by 0.0037 percent of viewers monthly online magazines. And while there are millions of blogs out there, relatively few of them attract the most readers. Various explanations have been considered sinister about it, but in reality is just one example of the power law distributions of power. As Clay Shirky has said: "In systems where many people are free to choose between multiple options, a small part of the whole will get a disproportionate amount of traffic (or attention, or income), although that none of the system members work actively to such a result. It has nothing to do with moral weakness, selling or psychological explanation. The very act of choosing, spread widely enough and freely enough, creates a power law distribution. "

This is the mathematical interpretations and political "power" merge into one. When blogging was dominant in the 90s, many people have speculated that the network would extend that Jürgen Habermas called the "public sphere", ie "an area in social life where people can come together to discuss and determine the social, and through this action influence the political debate.
