The myth that I find the most misguided: Writers should “dumb down” their content so everyone, everywhere can read it.
The first rule of writing is to write for your audience. Take their current level of knowledge into account, and use language they know and feel comfortable with. Don’t write for sixth-graders if your audience comprises physicians, small-business owners, or individuals with limited English proficiency. Write for sixth-graders if you’re audience is sixth-graders.
To write with your audience in mind, consider the following:
Identify your audience
First step is to make sure you know your audience. Don’t guess or assume. Ask yourself: Who is my audience? What does my audience already know about the subject? What does my audience need to know? What questions will my audience have?
Consider the format
Will your audience be reading your article in a printed newsletter or on a smartphone? Is it for an HTML newsletter or a blog. Format matters.
Consider the context
