The conversation of hypertext documentary really interested me. Brains statements about documentaries being about the world not a world showed that a large variety of things can be interpreted as a documentary. They do not all have to be in the same form as the whole world is not in the same form.
Another topic of interest to me was the development of things that are popular. Just because hypertext is not yet a popular mean of communication when it comes to documentary and in fact other things, does not mean that it is not a valid and effective form.
