good old wikipedia
Six degrees of separation refers to the idea that, if a person is one “step” away from each person he or she knows and two “steps” away from each person who is known by one of the people he or she knows, then everyone is no more than six “steps” away from each person on Earth.
Internet and computer networks
In 2001, Duncan Watts, a professor at Columbia University, attempted to recreate Milgram’s experiment on the internet, using an e-mail message as the “package” that needed to be delivered, with 48,000 senders and 19 targets (in 157 countries). Watts found that the average (though not maximum) number of intermediaries was around six. This finding is surprising, given the worldwide nature of the Internet.
It has been suggested by some commentators that interlocking networks of computer mediated lateral communication could diffuse single messages to all interested users worldwide as per the 6 degrees of separation principle via Information Routing Groups, which are networks specifically designed to exploit this principle and lateral diffusion.
so every 3 people there is some bacon :gotme:
