That does sound like it could result in an improvement, but the tree would grow quite large I imagine! :) Each writer would have to read each horizontal version to decide where to continue, and I'm betting there would be multiple continuation points, too, so it would start to look like the exponential story, especially with a virtually endless supply of writers. Crowd-sourced writing is a fun idea, but I think at best it might be an activity writers do to stay creatively loose.
