Imagine a team of reporters – together with witnesses on the scene – able to contribute photos and news to the same Wave (formerly known as a story or a page). One can write up what is known; a witness can add facts from the scene and photos; an editor or reader can ask questions. And it is all contained under a single address – a permalink for the story – that is constantly updated from a collaborative team. [..] Wave takes this to the next level. It combines the notions of a process as people add and subtract and update; it has the benefit of a wiki – a snapshot of current knowledge; it can be live; it can feed a blog page with the latest; it can feed Twitter with updates; it is itself the collaborative tool that lets participants question each other.
