This was a very helpful lecture for me. I was so happy that you taught me at least what not to do while I was just starting to think about good design. Also, since you provided sources for all quotes, I think it was a better lecture because I learned a lot of good books. Aside from the lecture content, the tone and lecture progress were neat, so I enjoyed listening to the latter half where you explained many terms. Thank you so much for making such a great lecture!
