After reading TCT Chapter 12: Revising and Editing for Usability, and Instructor Commentary: Usability, respond to these works in a comment of approximately 300 words. For example, you might identify particularly helpful or confusing aspects, or mention passages that seem especially relevant in the context of our project. In your response, make sure to point to specific parts of the readings, and use concrete examples (of instruction sets, of experiences with images or desktop publishing, etc.) to support your statements.
