It's dizzying thinking about all the existing things that Wave could replace, let alone the novel things that could be built on it. Out of the box, it's email, instant messaging, a blog engine, a wiki and Twitter. With an extension or two, it becomes any kind of social tool you can imagine. It sounds too good to be true, but that's because we've been obsessed with the web for so long that we've become blind to just how backwards it is for the things we want to do. If we want to build social tools, of course we should start with a social platform and build little tools on top of it.
