fair point. For tactical info, I'd look at Eval Kelly. He has got this 200 word article style down. A lot of his content is hyper-focused. He could easily write a LOT longer articles, but he chooses to write short ones to test his ideas.

Pay close attention to how he specifically calls out the person who the article is more, the problem he's solving, and the promise he's delivering. Those 3 things are what makes writing short articles "good".
