Gladwell takes a lot of heat as pop science author. The reputation may or may not be earned. But in 'The Tipping Point' he has done something very useful for people seeking practical ways to generate momentum or get themselves or their projects unstuck. Gladwell's book looks for points of leverage in the process through which an idea spreads and takes hold within culture. Gladwell is trying to find the most broad reaching and consistently useful points of leverage so that people attempting to create social change can use them as ready made tools of change. Is the book a deep read, no it is not. It is deliberately shallow on everything that it looks at, this is intentional. 'The Tipping Point' is not deep because it is broad- and the reasons for such a difference in approach are perfectly valid given Gladwell's intent in writing the book.
