If nobody reads it, you might be wasting effort by washing it down for public consumption, and possibly erasing valuable information as well. Might as well keep a private diary where you tell all.

If we accept that nobody's going to read it, then the content doesn't have to tell it for the audience. Not the content, nor it's tone or style or anything else. You can use obscure references that only you understand as a shorthand, like words that your family made up when you were small.
