This reads as an extended justification for how the author could possibly have failed. He writes as though it <i>must</i> be as simple as 'just should have asked a question'. It's an odd conclusion which communicates its own set of assumptions. It reminds me of people who claim, in all seriousness, that they can always spot X intangible characteristic — without any justification for how they determine their false positive/negative rate in that judgment. This undoubtedly reflects my bias, but I find many (bordering or even definitely including most) 'humble' blog posts to do this; and that is perhaps a further riff on the kind of canned advice we see here. They tend to read, to me, like answers to the interview questions, "Tell me about a time you failed," or, "What is your greatest weakness?" In this case, all the author really reports is that he did extremely poorly relative to his expectations — but he manages to spin it into a maxim. If even someone as qualified as he could be unseated by this tactical error, it surely bears memorializing as advice worth living by.
