Here's a nice film promoting Charles Leadbetter's new book "We Think". The book is about collaborative innovation on the net.
From Mr. Leadbetter's site, "Welcome to We-think: mass innovation, not mass production
WeThink explores how the web is changing our world, creating a culture in which more people than ever can participate, share and collaborate, ideas and information.
Ideas take life when they are shared. That is why the web is such a potent platform for creativity and innovation.
