Rizzoma allows communication within a certain context permitting a chat to instantly become a document where topics of a discussion organized into branches of mind-map diagram and minor details are collapsed to avoid distraction.

Actually I think that is what a lot of systems are moving towards... a real-time outliner/wiki.

Google Wave just felt toooo real-time and free-form.
