A new type of new media could be a collaborative site that will allow users to create projects together. It would be a sort of google docs but based on a site. Unlike google docs, other people would be able to comment on the project. They would have to prove that they know something about the subject so it wouldn't be completely random people, but knowledgeable perspectives.
This could be used for professional projects as well. Just because you might not personally know someone, doesn't mean that they don't have anything positive to contribute. If a businessman was working on some presentation, another businessman from some could comment and add pictures, idea, etc.
