Is there a name for a style of writing where the author "speaks" to an imaginary reader in an imaginary conversation?
Example
When you write for web, you should keep your paragraphs short and your sentences shorter.
But, why? That's not what I learned in school. Long sentences mean you're smart, right?
Well, it's harder to read on a screen. Shorter paragraphs and sentences are easier to read. If your content is easier to read, a user is more likely to keep reading. If a user keeps reading, they're more likely to use your service or at least remember your name and brand.
In the example above, the first and third paragraphs are the author, and the second is the _______? Every time I've seen this in writing, the author has referred to the speaker as "imaginary reader," but I feel that this specific style should have a name.
If it were music, I'd call it "call and response" (think "Dueling Banjos"), but the term doesn't specifically refer to the writing device.
