He posts to his blog about GA too:

And, he has a website dedicated to PGA:

I tried reading this book. There are no practical examples of how to calculate anything useful with geometry algebra in Chapter 4. This seems rather odd because Chapters 1-3 are very practical, including both equations and code examples.
