1. What is the principle of six degrees of separation? What number of social links does any one person need to be connected to global society? p. 30
"Six degrees of separation" means that a person is separated from a randomly selected person by six acquaintances on average, and it implies we all live in dense networks of people. In order to connect global society, we just need more than one social link.
2. How is the fabric of society today different from pre-internet society? p. 31
The fabric of society today is more densely stitched than that of pre-internet society because informational nodes are far more multiply connected due to the Internet.
3. How many more links separate any pair of web pages compared to people in society? What can explain the difference? p. 34
