The Long Tail, Longer is essentially an updated version of 'The Long Tail' but a longer version, duh. His acute observation on the dynamics of the internet and how it interferes with consumer behavior is backed by hard data, surely is convincing enough to tell us that human do not behave in a linear way when it comes to consuming data, information and products online. The days of sole pre-selection consumption is over. Don't get me wrong. Pre-selection will always be there because we cannot live online without a physical world but it does bend certain rules of traditional economics and marketing, making it possible to change the game entirely.
This is a must read book for those who love Malcolm Gladwell, those who love Barry Schwartz of 'The Paradox of Choice'. Too many choices in the physical world may not be a good idea as it overwhelms the audience. But online? There is no such thing as 'too many' or 'too much'.
