In many areas of life, the law of averages applies – most things are statistically distributed in a pattern that looks like a bell. This pattern is called the "normal distribution". Take human height. Most people are of average height and there are relatively small number of very tall and very short people. But very few – if any – online phenomena follow a normal distribution. Instead they follow what statisticians call a power law distribution, which is why a very small number of the billions of websites in the world attract the overwhelming bulk of the traffic while the long tail of other websites has very little.
