Knowing everyone: Are you a connector?

In "The Tipping Point," author Malcolm Gladwell argues that the success of any kind of social epidemic depends on the involvement of people he calls "Connectors." These are the people who know everyone.

Mr. Gladwell offers the following list of surnames taken at random from the Manhattan phone book. Give yourself a point for every surname that is shared by someone you know -- by the author's definition, "if you sat down next to that person on a train, you would know their name if they introduced themselves to you and they would know your name."

Multiple names count. If the name is Johnson, and you know three Johnsons, you get three points. Your score should roughly represent how social you are.

In his book, Mr. Gladwell says scores tend to vary by age, with groups he tested averaging about 21 for college students and 40 for professionals in their 30s to 50s.

Connectors, on the other hand, score very high in every age group, with some hitting 90 to 100 and more.
