I enjoyed the course very much. The course is structured into several relatively short sections in comparison to other courses I've taken in Coursera. At first, I was apprehensive about this but I came to like it. The instructor is both knowledgeable and enthusiastic. The interface allows students to code right in it, and even though I mostly followed in my own editor, this can be a nice feature for other people. I like the fact that the instructor writes code during the lessons instead of showing slides. The interface also allows for easily downloading lesson files if needed. I also appreciated other resources mentioned through the course (webpage deployment, font and gif sites, color tools, etc.) and the optional bonus projects.
Most practice quizzes were not really challenging because most had only two questions and were fairly easy. It is not something that really affected me because I learned well with the lessons themselves. Graded quizzes were lengthier and overall much better than the practice ones. Finally, I feel the positive reinforcement comments are a bit much.
Overall, very nice course. I strongly recommend it.
