John Graham-Cumming, in his post, How to write a “Malcolm Gladwell Bestseller”, dissects the essence of Gladwell’s approach to bookwriting very successfully.
At first consideration, there seems to be something signfigant that Gladwell is attempting to say. But there is less there than it seems. It’s very good writing, and it is no worse and arguably much better than alot of business writing centered on case studies. But as this author says, they are a collection of interesting essays, and not a strong argument for some grand new idea.
