Long before it became the biggest collection of knowledge in the history of the world, Wikipedia had to overcome its greatest challenge: getting strangers on the Internet to trust each other. They had to trust that others would not be abusive or uncivil, that others would not unfairly change or erase their contributions, and that people had good intentions.

Jimmy Wales, the internet entrepreneur who founded Wikipedia, details the global experiment in sharing knowledge and expertise online that has become part of the fabric of our modern, connected life. It's all laid out in his new book, "The Seven Rules of Trust: A Blueprint for Building Things That Last." Jimmy speaks with Carol Massar and Tim Stenovec on Bloomberg Businessweek Daily.
