Loved it, but I felt a large proportion of the 'bubble breakers for software engineers' are actually referenced quite often on hacker news. Not 'Taking charge of your fertility' though.
“Taking charge of your fertility” is basically about how to gather and analyze data about your body’s functioning, in order to achieve a desired health outcome (specifically, pregnancy).
Yeh -- I do agree, though I suppose that shows that the HN demographic is broader than the stereotype of software. The fertility one's quite fun.
