1. The title does not make huge claims directly, but strongly implies it. That's how I read it when I was skimming the front page of HN. It's like writing an article with the title "I taught Michael Jordan basketball" and then explain how you showed him how to throw a ball for 30 minutes when he was the 5 years old. Or the old maxim that if you are a cashier at McDonald's, you can technically say that you "process high-frequency cash transactions for multi-billion dollar company on rotating supply-demand cycle".
2. I don't like how the common advice for writing resume, which I can only presume reflects what hiring managers want to see in someone's resume, says you must quantify your achievements. You cannot just say I wrote the login system. You must somehow tie it to a business objective and achievement (increases sales by 7%, reduced support calls by 12%, etc). In reality, projects are often team efforts and except for certain niches such as sales and consulting, there is rarely a clear correlation between an individual employee's actions and business's results. I don't like writing pretending there is and writing it, and I don't like reading it.
