G'day folks,
Researchers at IBM's Visual Comnunication Lab have published an interesting paper called "Talk Before You Type: Coordination in Wikipedia" at the 40th Hawaii International Conference on System Sciences held recently.

It shows an interesting representation of edit wars and looks at a strong growth in talk and user talk pages. It was posted on Chris Lott's blog which is also worth a look.
