If you don’t have time to watch the whole thing (just get through the first 40 minutes), it’s a demo of the new Google Wave; a system created by the developers of Google Maps that will revolutionize email and social networking.

Here are a few key features:
Wiki-style functionality – The video above can show you how this will work
Wave Extensions – Open source, third-party applications
Drag-and-drop file uploads
Wave Embeds You can put these conversations on your social networks or website
Playback – Allows for you to see the evolution of an email
Open-source – allows developers to improve the existing code

The most exciting part of this will be the Wave embeds. Imagine a community on your site that allows fans to contribute to the conversation, uploading pictures, videos and opening the door to collaboration.
