16.2 Hypertext and Hypermedia
Golden Rules of Hypertext:
-
There is a large body of information organized into numerous fragments.
-
The fragments relate to one another.
-
The user needs only a small fraction of the fragments at any time.

-
Too many links

Long chains of links to reach relevant material

Too many long dull articles
