Market Place 3.0 rewriting the rules of borderless business, by Mikitani Hiroshi, CEO of Ratuken, is a book well worth your time and energy.
I have added it to my recommended reading list which you can download here.
I loved the book because it contains great insights and very doable tips about real empowerment, company culture, social-media, ecommerce and how fun can be profitable.
I particularly enjoyed Mikitani's reflections on "service-mind", how the internet is much more than a modern vending machine, and why and how the human face must be present in all the online aspects of our organisations.
Be the difference you want to see in the world.
