I found the video interesting. I don't think any particularly new concepts were raised - we have been searching for some time to find ways to deal with the concepts of authorship and identity on the web. However, I like the brief history of why it happened. While I understand the overall idea of the web, the specific information of the changes that have led us to where we are today, I appreciated.
As for the audience, the people viewing the video must have a concept of the possibilities of the web or it will be pointless. I also think that people who have grown up with the web, may benefit from it because they may not understand the scope of the change and the vast implications for society.
