Google Wave

Google Wave is a new communication service previewed today at Google I/O. "A wave is equal parts conversation and document, where people can communicate and work together with richly formatted text, photos, videos, maps, and more."

The service seems to combine Gmail and Google Docs into an interesting free-form workspace that could be used to write documents collaboratively, plan events, play games or discuss a recent news.


Google Wave has been designed by the founders of Where 2 Tech, a start-up acquired by Google to create a cutting-edge mapping service, which later became Google Maps.

"Back in early 2004, Google took an interest in a tiny mapping startup called Where 2 Tech, founded by my brother Jens and me. We were excited to join Google and help create what would become Google Maps. But we also started thinking about what might come next for us after maps. As always, Jens came up with the answer: communication. He pointed out that two of the most spectacular successes in digital communication, email and instant messaging, were originally designed in the '60s to imitate analog formats — email mimicked snail mail, and IM mimicked phone calls. Since then, so many different forms of communication had been invented — blogs, wikis, collaborative documents, etc. — and computers and networks had dramatically improved. So Jens proposed a new communications model that presumed all these advances as a starting point.

"In Google Wave you create a wave and add people to it. Everyone on your wave can use richly formatted text, photos, gadgets, and even feeds from other sources on the web. They can insert a reply or edit the wave directly. It's concurrent rich-text editing, where you see on your screen nearly instantly what your fellow collaborators are typing in your wave. That means Google Wave is just as well suited for quick messages as for persistent content -- it allows for both collaboration and communication. You can also use "playback" to rewind the wave to see how it evolved."
