Has anyone seen an "overview of the design/possibility space" for group writing? For illustration, single authors have interacted with support communities in a variety of ways, from blogging almost complete chapters, to discussion forums brainstorming plots and characters. What are some others? And how does single and group authorship blend, given early readers, and writing groups, and collaborative research, and so on? I don't have a feel for the design space. This post prompted the thought that it's richer than I'd been considering. I've failed at creating social infrastructure for a hobby project around transformative improvement of science education content. It seems clear I'd need a diverse hybrid of multiple support processes, but the path to minimum viable process has been a challenge. So I'm hoping for "oh... that's an interesting possibility I'd not considered" fodder, as I found this post to be.
