This original conception of hypertext fathered two lines of descent. One adopted hypertext as a practical tool for organizing and cross-associating information; the other embraced it as an experimental art form, which might transform the essentially linear nature of our reading into a branching game, puzzle or poem, in which the reader collaborates with the author. The pragmatists use links to try to enhance comprehension or add context, to say “here’s where I got this” or “here’s where you can learn more”; the hypertext artists deploy them as part of a larger experiment in expanding (or blowing up) the structure of traditional narrative.
These are fundamentally different endeavors. The pragmatic linkers have thrived in the Web era; the literary linkers have so far largely failed to reach anyone outside the academy. The Web has given us a hypertext world in which links providing useful pointers outnumber links with artistic intent a million to one. If we are going to study the impact of hypertext on our brains and our culture, surely we should look at the reality of the Web, not the dream of the hypertext artists and theorists.
