I was looking over this lecture to find a slide, and it was incredibly fast, because you can just glance at the titles.
Also, a lot of people will take up a huge portion of space on each slide with colorful frames/borders, and a huge stamp at the bottom branding the slides like "CMU".
I appreciate the simple formatting, and modest watermark on the bottom right, which makes it easy to focus on the slide.
I agree, these tips by Kayvon are very reasonable and impactful. It will surely be helpful throughout my life.
