Caroline Jarrett on User Interface Design
Jarrett is one of the authors of User Interface Design and Evaluation, a beginning text for technical communicators moving into user interface design. Jarrett says this book is a perfect start for users looking to add usability basics to their toolbox. She also talks about forms, and how the best forms are ones you barely notice.
