I’ll be the jerk here: I’ve stopped reading articles that include the word "lesson" unless they provide tangible impact metrics—like how much money you actually made as an indie dev. I have skimmed the article and to me it is generic. It might sound harsh, but that’s the reality. Hacker News has become nothing more than a launchpad for new apps and services. These posts are often just veiled advertisements, like yet another "Show HN: Timelines.app."
