It seems more than one HN user finds it amusing that this guide covers "rudimentary" things like predicate logic and word problems. Keep in mind that these are the skills the Secret Service wants their applicants to actively get better at before applying; it just so happens that already having these skills are common in the HN community. I'm sure the community of Secret Service applicants finds the skills they are good at for which the HN community needs to actively get better at equally amusing. Social aptitude and physical fitness for example... Maybe I'm getting old but my preference is to not cast stones at communities that are different than mine.
