While it's true that reading one article, be it on HN or TC or wherever else, won't make a huge difference, what makes a difference is the aggregate of gleaning what information you can over a long period of time. Much like most (real) classes, you can't really cram, but as you continually ingest information it becomes a part of you. Coming from the business end of things before I started programming, I learned about IPOs not from business classes but from reading about which companies would IPO. I learned about vesting schedules and cap sheets by reading about people discussing these things. While it's taken years for me to feel like I understands most of the ins and outs, it's also something that you really should be learning second hand. You don't want to be talking to a potential investor and have to ask him what a cap sheet is. It's not about, "I will read this and understand," it's about immersing yourself in the culture and picking things up as you go.
