I recently stumbled across a very neat little blog commmunity aptly titled The Creating Passionate Users. This community of bloggers claim they are fascinated by brains, minds and what science can tell us about the practice of making users passionate about their lives and tools. The community is co-ordinated by Dan Russell, a full-time research scientist and software developer at Google who has a PhD from the University of Rochester in Artificial Intelligence and Kathy Sierra who has been interested in the brain and artificial intelligence since her days as a game developer (Virgin, Amblin', MGM). Crash course in learning theory looks at blogging as an educational tool rather than a sales or self promotional tool.
