At the beginning of 2000 Little, Brown published “The Tipping Point” by Malcolm Gladwell. It was an auspicious time for both the calendar industry and the publishing world. Mr. Gladwell had a deductive style and a teacherly simplicity that would make him one of the new century’s most frequently quoted and widely imitated writers of nonfiction. He went on to write “Blink” and “Outliers,” and all three books went to the top of best-seller lists. What can this tell us about Mr. Gladwell or about the people who read him?
