Keith Ferrazzi. "Never eat alone" and other rules of networking (№ 382310)

As a result of Granovetter became popular expression "the strength of weak ties".
Its meaning is that when it comes to getting a job (or, for example, new information), the "weak" links are usually more important than "strong". Why is this happening? Think for yourself. Many of your closest friends attend the same party as you, go with you to work in the same office, that is, live in the same world with you. Therefore, they rarely have any new information for you.
