Dan Gillmor on Storytelling

In the introduction to his book We the Media, longtime journalist Dan Gillmor writes:

This book is about the transformation from a twentieth century mass-media structure to something profoundly more grassroots and democratic. It's a story, first, of evolutionary change. Humans have always told each other stories, and each new era of progress has led to an expansion of storytelling.

This is also the story of modern revolution, however, because technology has given us a communications toolkit that allows anyone [to] become a journalist at little cost and, in theory, with global reach. Nothing like this has ever been remotely possible before.

So I ask: What is happening as this evolution meets this revolution? Is the world changing because of it? Is journalism changing because of it? And if there is change happening, is all of it change for the good?
