3 degrees of seperation
Cow’s blog brought my attention to this bit of research from O2. They say that (within a shared ‘interest’ network) there are no longer 6 degrees of separation but now only 3, due to the rise in telecommunication and social networking. They say email and mobile phones had the most significant impact.
“All respondents were asked to make contact with an unknown person from destinations selected at random from across the globe using only personal connections. By using their shared interest networks the participants were able, on average, to make the connection in three person-to-person links.”
