InformationWeek: Google is adding a new feature called "Discussions" to Google Docs to make it easier for business users to work together on documents. Docs already had a built-in comments feature, but the company says that discussions is even better. The discussion comments open in a separate window pane and track downward so that users can see who said what and when. In addition, there's a resolve button to mark when issues have been sufficiently addressed.
Google's Scott Johnston describes the new feature as a way to "accelerate collaboration."
