> there is a lot of noise here

This is true. However, much of what I know about how software development can work, I've learned from reading HN. I've learned loads about cloud, containers, micro services, project problems, etc. This helps me understand all the discussions around me while I was a junior and allowed me to successfully lead development of a SaaS product. If I just focused on learning a single thing, I wouldn't have been able to grasp all the other stuff that is necessary to actually build a product from scratch.
