If you love em dashes and commas you will also love this https://archive.ph/0dxpW from the newyorker by Mary Norris.

I was never a big reader as a kid, but I fell in love with the New Yorker, much later in life, where I kind of adopted their idea of: "Once you understand them, you can read through long sentences very easily". That is the newyorker style of writing. One falls into two buckets, you love that kind of writing or you hate it. If its the latter, you should adopt em-dashes and commas to improve your writing style.
