1. Wiki Style Functionality
The feature: While Google Wave works a lot like email or IM, there is a huge difference: you can edit not only your messages, but the messages of anybody within your wave. You can reply to messages within a conversation string and reorganize conversations.
Why it’s game-changing: There was a perfect example of how this changes communication during Google’s demo of the product. A group of people are trying to plan a group dinner, and want to see who can come or not. In email, you have a string of emails with yes or no, which can get messy.
In Wave, you can edit the original message with a section with who can or cannot go. Replies can be made within a conversation string, rather than at the end, making conversations a great deal easier to track.
