An open question for WeWrite's design direction is "how can authors get feedback on their writings?"
Backlinks or "What links here" could populate polemics or responses to a piece. An author could even go so far as to promote these responses in their own piece, creating a continuous timeline of how the discourse unfolded. These responses could be added to the original post by others, and submitted for approval to the original author. An author who is willing to confront serious responses would approve such edits.
The collaborative aspect will turn readers into participants in the process of knowledge-creation and worldbuilding.
Live chat could allow for rapid-fire feedback on a page, although this might not be a good idea given that we ought to promote new writings and synthesis of new ideas.
