Tiesto and the six degrees of separation theory

Good old Tiesto made a nice video about the six degrees of separation theory. After 10 seconds on google I found the following description of the six degrees of separation theory on Wikipedia:

The small world phenomenon (also known as the small world effect) is the hypothesis that everyone in the world can be reached through a short chain of social acquaintances. The concept gave rise to the famous phrase six degrees of separation after a 1967 small world experiment by social psychologist Stanley Milgram which suggested that two random US citizens were connected on average by a chain of six acquaintances. More information on the subject can be found at Six degrees of separation and Small World Phenomenon.

Since there are so many social networks I wonder if anyone ever considered checking if the theory is actually true. Or maybe the actual degrees of separation might be less because the introduction of internet throughout most of the world. Then again, I don’t know what definition of ‘degree of separation is. In other words is an internet connection a connection within the definition of ‘degree of separation’ as meant by Stanly Milgram. Anyhow, Tiesto made a nice clip to illustrate the concept (Dance4Life).
