There is more to writing than just the content. The history and the background of the author plays a significant role. Let me give some reasons WRT this article: 1. In this article, the author says that he does not know streams. Now, when he learns it well, he can write about "How he learned about streams", and a beginner would empathize more with this article rather than some expert ranting about it in their blog. 2. It is inspiring for the readers. It sends a message: "If you master one skill and master it well, you can still add a lot of value to the world. Knowing everything in the field is not really important". 3. Many people write not just for others, but also for themselves. Making your insecurities public is a good way to acknowledge and face them.
