You know the blog, now watch the Channel 9 video featuring Damien Watkins, Rick Molloy, and Don McCrady. I like this one because they talk about how they ended up changing their minds over the course of development, moving from a language-based approach to a libraries-based one. They get into why that's better and what C++ 0x features they needed to make it possible. A nice way to spend a little under an hour.
