Up until four years ago, your notion of "what's necessary" was the law of the land. Starting from sometime around Hemingway, we produced a century's worth of flattened, easy-reading slop, and much knowledge was shared very widely. There was a certain art to the blandness. (One notable master of that art is pg, the creator of this website.)
Then we fed that slop into a giant machine that makes it trivial for anyone and everyone to produce that sort of generic writing. If you want to change minds and differentiate yourself now, you can't just do the old flat style anymore. You have to set yourself apart somehow, and you can start by loving the craft of writing again.
The people who matter will read it and love it. Everybody else can take what you wrote, dump it into the slop machine, and rearrange it into something they find easier to read.
