The problems Wave solves
I believe that people who don’t see what Google Wave is for are simply looking at it from the wrong angle. Wave is not a social tool. It’s not Twitter, it’s not GTalk, it’s not Facebook. It was never designed to appeal to the crowds of geeks who are currently trying it out. Wave is built for the corporate environment. It’s a tool for getting work done. And as far as those go, it’s an excellent tool, even at this very early stage.
