Another digital storytelling-related question.

How does the inclusion of relationship elements engage the reader?

Naturally, everyone wants to be a part of something. We all like to think that certain things are created solely for our own use and benefit. If a reader has personal interest invested in a piece- or a "relationship" with it, if you will- then the reader will automatically become more involved in the piece. The reader will be more inclined to read it, finish it, and share it with others if it's something that really affects him or her and strikes a note within that reader's mind.

Interrelated stories create a sense of continuity. Theoretically, an interrelated, interlocking story never has to end. One story may branch off into other, creating a series of spinoffs which will keep the reader's attention for a long time.
