|Down to the business of taking a breath|
The state of commas is in decline, at least. Commas are becoming less frequently used, and more commonly misused. Their purpose is mainly to signal a pause, set apart adverbial clauses, distinguish components of a list, and piss proofreaders off.
Too often, they are either sprinkled in wild abandon or absent in a breathless sentence.
Be intentional with your commas. Pause, at times, for effect.
