Query: Insightful and informative

Very interesting read. I am surprised that although I have seen the book quoted umpteen times, I have not seen its findings touted as much (max 150 number people circle, etc). I think its concenpts could be great for marketing people who could depend on 'connectors', 'mavens' and 'salesperson' concepts to extend the reach of their marketing arm with minimal effort/cost. However, the book introduces a significant knowing-doing gap for the average reader. The reader is left amazed by the insightful knowledge but is also left frustrated not knowing how exactly to apply it.
