Reading Reflection No. 3

For the third reading, I have read Chris Anderson's The Long Tail: Why the Future of Business is Selling Less of More.
1)
This book introduces the theory of the "long tail". The "long tail" stands for the largely forgotten niche markets in contrast to "fat head" which means the most popular markets. When "long tail" products are properly marketed, the combination of a variety of such products can be as popular as those that belong to the "fat head".
2)
I think the theory of the "long tail" is essentially about the optimization of the arrangement of the sources. Entrepreneurship itself is about maximizing the effect the limited source could produce.
3)
The exercise would be creating a social media account for the business and try to market with it.
4)
I'm surprised that this book's contents contain about 80% of unuseful information or over-interpretation of extremely simple ideas. Even this also applies to the Pareto Principle XD.
