Google introduced yesterday their idea of reshaping the future of communication on the web called Wave. It’s totally yummy and also open source.

According to their sneak peak page,

A wave is equal parts conversation and document. People can communicate and work together with richly formatted text, photos, videos, maps, and more.

A wave is shared. Any participant can reply anywhere in the message, edit the content and add participants at any point in the process. Then playback lets anyone rewind the wave to see who said what and when.

A wave is live. With live transmission as you type, participants on a wave can have faster conversations, see edits and interact with extensions in real-time.

Enjoy the deliciousness of their 1:20 hour long presentation-demo

And of course, it comes with an API too.
R.I.P. Twitter.
