- Kim Spinder is an innovator and 'pirate'. She won The Harvard M-Prize for Management Innovation, founded Deelstoel.nl, and the Open Innovation Festival. She is a very popular speaker. She herself stopped using email on January 1, 2011. Since then her life has changed dramatically and this book may change yours forever too. Let's break the endless cycle of email. After all, it was not invented as a tool of mass communication. It is best used for sending documents and one-on-one communication. But as soon as you need to communicate with more people, email becomes a monster. Luckily there are many other tools and forms of communication that are far more efficient. Kim Spinder offers an email 'reduction diet' and program for quitting which suits people who want to try it out, as well as the radicals who stop using it completely. A very refreshing and rebellious book.
