I doubt that anyone is overly shocked at this, but it does underline indeed that Wave is confusing, and most people are not sure how or why to use it. I am a part of some 60 Waves now, and have really used three. Wave has yet to find its killer application.
It will, but whatever we will be using Wave for one year from now, does not exist yet. Either Google or developers need to guide us out of of the dark. We want to walk, we just need some light.
