I agree that they were missing some core features in the beginning. It has greatly improved though. They've opened it up now so that you can design a better interface if you wish to. They've also opened it up to anyone with an email address now, and expanded on the robots and gadgets. Now I don't use Wave that much because I don't often need the collaboration that it offers. However, if they could integrate Wave and Gmail, it would be immensely useful, especially the gadgets and robots.
