We all know bad writing when we see it: schlock, puffery, needlessly elongated words and phrases, meandering, poor word choice, corporate ipsum, and on and on.
Bad (or so-so) writing sometimes manages to get through as effective communication, but bad communication can be tougher to spot — especially when it’s well written.
All writing is for an audience. If the writing is purely for your own enjoyment or edification, go ahead and do what works.
But if the writing is for anybody else, the words, the structure, and the format have to be meaningful to the person you’re seeking to change.
Write as well as you’re able, but by all means write as effectively as you can.
