I think it would be interesting if you could share your google docs through Google+. Imagine working on a book (or a school project): create a circle around that, then share your latest work with the circle. Anytime someone wants to annotate or change something, they all have access to the same file and comments/hangouts/etc. can be made around it. Sci-fi and fantasy authors do this frequently albeit through email, and online book clubs.
