Google Wave: A new model for communication and collaboration on the web, coming later this year.
Wave is equal parts conversation & document. Users can almost instantly communicate and work together with richly formatted text, photos, videos, maps, and more.
Also a platform with a rich set of open APIs allowing developers to embed waves in other web services & build extensions that work inside waves.
This is the Real-Time genre honey!! I only wish Peaceful, Positive & Knowledgeable collaborations to Unite All 🙂
