The moral of a story which has one is part of its story, not its meaning. It is unreachable and thus not yet linked. Every reading by every reader becomes privileged and authorized. The reader cannot avoid adding her own meaning to the document. Addition is not merely privileged but required in order to span to the nethermost, target node outside the text.
Interaction is perception of the principles of ordering.
Because hypertexts are read where they are written and written as they are read, interaction is the assumption of authority over the replacement of one writing by another. The reader's orderly perception leads to the placement of an apparent meaning. Under such circumstances, each addition is an initial node to the replaced story she tells in her reading. The meaning of a story which had none becomes part of its story. Despite these heroic claims, readers are thusfar not particularly apt to participate in maintaining, i.e., co-authoring, narrative hypertexts.
