The idea of creating arbitrary (or idea-based) structures online really interests me in this posting by Dave Winer. The chronology of a blog or linkblog stream is a real virtue, but it doesn't organize content by ideas the way a nonfiction book chapter often does. If the outlining community could figure out how to keep the advantages of chronology for recording work in progress and engaging with others on the blog while at the same time finding a tech and workflow solution to reorganizing that content into larger things with idea-structures, like chapters, that would be a real breakthrough. This is very interesting to muse over for a solo writer's own projects as well as for collaborations that might take place between groups of writers and even groups of sites. Also useful to think about here is the input/output or creation/publishing distinction in a blog post by Chris Wolverton.
