Connector noun con·nec·tor [kuh-nek-ter]
“Connectors, are the people in a community who know large numbers of people and who are in the habit of making introductions. They usually know people across an array of social, cultural, professional, and economic circles, and make a habit of introducing people who work or live in different circles. They are people who "link us up with the world ... people with a special gift for bringing the world together." They are "a handful of people with a truly extraordinary knack for making friends and acquaintances". "Their ability to span many different worlds is a function of something intrinsic to their personality, some combination of curiosity, self-confidence, sociability, and energy”.
