Google Wave is a real time communication & collaboration tool that is termed as the next evolution of email.  It combines aspects of email, instant messaging, wikis, web chat, social networking, and project management to build one elegant, in-browser communication client. You can bring a group of friends or business partners together to discuss how your day has been or share files. A wave can be both a discussion and a document where people can discuss and work together using richly formatted text, photos, videos, maps. Wave builds on the concept of cloud computing.
