While some authors write specifically to make an argument to an audience, many others write because they want to follow their personal muse. Sometimes writing is a catharsis, or an exploration of self. Sometimes writing is a sharing of experiences, fragmented images, or just of a point of view. Sometimes writing is marking a path for an audience to follow, or perhaps just presenting emotional material the audience can form into its own vision. Interactive communications challenge the power of a linear story itself, and justifiably so. There are many ways to communicate, and each has just as much value as the next depending on how one wishes to affect one's audience.
