Is not the entirety of this perceptible world a "highly dense information surface"? How can we make this sort of distinction? Within a single frame of a conventional linear film, we may already be confronted by extremely dense and complex sets of "information" — textures, patterns, objects, distinguishing features of specific characters...

It seems that "density" is not the most important feature of new hypertextual environments. We are exposed to infinitesimal levels of information density in "the real world" and this is hardly new. To say that linear, single streams of information are necessarily basic and 'non-dense' is to make a sweeping assertion. Thus hypertextual environments are not intrinsically "denser" than any other forms of information surfaces, the question of density is superfluous. Instead, it is the number of streams of information that one must process simultaneously that is a new variable within digital and hypertextual environments. The experience of streaming video content in one window while listening to music in another and writing an email in a third is one that typifies the manipulation of a computer GUI.
