Developing for Google Wave

In the last couple of weeks I've begun researching Google Wave and developing some simple robots for it.
One thing I've found is that there aren't many articles discussing developer related topics for Google Wave - especially when it comes to clarification of some of the API things, or elements which may not be fully documented.
The Google Groups are great, but slightly limited, so i'm hoping to use this blog to both ask some questions and also post things I find out which don't seem to be fully documented elsewhere.
