Google continues to impress me. Not just with their web applications but with their documentation as well.
I recently read about the development history and philosophy behind Google's new web browser, Chrome. But it wasn't any sleep-inducing white paper filled with techno-speak (my apologies to those who love reading white papers). It was a 37-page graphic novel by comic book artist Scott McCloud (his 1993 book, "Understanding Comics" is a great analysis of the medium). Scott's clean, demonstrative style allowed me to understand complex concepts (such as multi-process architecture) and helped me appreciate all the hard work that goes into developing an application.
I can't wait for "Chrome" the movie.
