The wiki experiment is now going in a very interesting direction. British publisher Penguins has started a new experiment for using the wiki idea to creat a novel. You can participate in this experiment by visiting this experimental site.
Wikipedia seems easy to grasp in comparison to a wikinovel. I am eager to see how this experiment progresses. This is definitely going to me interesting than the interactive novels or movies in which a person could select one of the alternatives and go in that direction. In that case there was just one author with multipe plots. Here multiple authors will converge to one plot. Kind of intriguing idea.
