It's fine to not know it. It's absurd to judge the merits of an article based on not knowing a word it uses. I mean seriously - you're going to judge an article based on a word YOU happen to not know? Farcical to the extreme.

Made me feel like I'm in that movie from the 90s, "Dexter's Lab Ego Trip" when they are using square wheels instead of circles.

Imagine getting in a "tizzy" about journalists using the word "tizzy"... that's irony for ya.
