I don't know whether Shivanic's article is insightful or just cranky, but these three sentences struck me as true:
"If we don't understand bad writing, we can't understand good writing. Bad writing is characterized by obfuscation, showboating, narcissism, lack of a moral core, and style over substance. Good writing is exactly the opposite." -- Anis Shivanic, "The 15 Most Overrated Contemporary American Writers" (Huffington Post).
