This was a topic from the first chapter of the book, and the cobra effect example using Instagram was very impressive. For me, who uses Instagram not just as a simple SNS but as a tool for acquiring information through its algorithm features, it's useful for obtaining various information beyond what I need to learn, but time management was a challenge. I went back and forth between deciding and acting on firmly banning SNS use, and when I read the content in the book, I felt the irony in how the situation reverses when you deliberately try not to use Instagram haha. So it wasn't just me;; Since I'm a non-major student, I regularly review and study Figma materials, but these days Figma's update cycle is so fast that books don't match up. I'm wondering what to look at in times like these. YouTube is also perfect for filling in my lacking design knowledge, so I frequently check it out. Through Dinon author's reading challenge, it was a very precious time that allowed me to broaden my UX knowledge more beneficially. I think that even after the challenge period ends, if I continue to regularly find and read UI/UX related books and organize my thoughts in writing like now, it will be better remembered and become a study resource. Highly recommend it.
