I apologize for getting stuck on your parenthetical but while pithiness is a fine aspiration in a North American business setting, pithy reads generally can't exist without more detailed and nuanced long-form analyses, and the latter face a more dire existential threat. You are right that pithy [writing] is an important skill, as are slow and deliberative reading and writing of longer form work
I'm not claiming the original post is detailed or nuanced, to be clear
