I personally learned some of this in my UX course, but nothing substitutes for experience. As is, the article is seems to be extolling the virtues of keeping good feedback practices in mind (as well as highlighting a rather amusing term, "grinfucked").

of course, that's trained human behavior. the post was a reminder to constantly elicit direct feedback from the end user and constantly collect data.
