There is also a temporal difference for writers in different the mediums.
Text is mostly a solitary pursuit in which authors complete and publish the work.
This is where authors let go of their active part of the narrative, and the rest is in the hands of the readers.
In the case of a CD-ROM, hypertext also has a ending point, where the product is released to the public.

But with the internet, the ending point blurs.
The "final" is more ephemeral.

Authors can continue to change the work, even as readers are engaging the story. In fact, with the advent of
XML (Extensible Markup Language),
ASP (Active Server Pages),
Java and other technologies on the web,
dynamic interactivity in webpages can be automatic and determined by the readers themeselves.
So, this node could be automatically and dynamically (re)arranged anew everytime someone "reads" it.
This can be done both individually and collectively, as the website (and the arguments therein) respond to the readers.
A hypermedia document on the internet is an organic and rhizomatic experience for both readers and writers.
