The Creating Passionate Users bloggers are all fascinated by brains, minds and what science can tell us about the practice of making users passionate about their lives and tools. Kathy is the co-creator of the bestselling Head First books (the brain-friendly series from O'Reilly), and creator of the Creating Passionate Users blog.

They're all passionate about the brain and metacognition, most especially--how the brain works and how to exploit it for better learning and memory. Oh yeah, and how to recognize when someone else (including one of us) is applying brain-based techniques to get you to do something.
