Claire Bolderson profiles the founder of Wikipedia, Jimmy Wales, who is working as an unpaid advisor to the UK Government helping open up policy making to the public. He's an information evangelist and his belief in the power of shared knowledge has driven the remarkable success of Wikipedia, the online encyclopaedia. With entries on more than 20 million subjects looked at by more than 450 million people per month, Jimmy Wales' creation is one of that handful of internet successes that really have changed our lives. The programme hears from associates of Jimmy Wales and from his critics. And of course from the man himself.
