First off, I really enjoyed Deigo's introduction. I must sau that my attention was captured by the speeding driver scenario. This is good because it totally applies and we've all seen it. It just put me in the story.
Brad had a great way of defining his enemies, "...now a new, cruel digital TA is
working for the teacher that never sleeps and is constantly bossing students around." That is very entertaining. Also this works effectively to turn us against online quizzes and the like by personifying them as all we imagine in horrible TA's.
