This document discusses different styles of communication used within companies versus with the public. Internal company documents like memos and meeting minutes use intracompany vocabulary and an active voice. External documents like press releases and websites use more regular vocabulary and are less formal. Reports to the public focus on facts and statistics using an 11th grade reading level without emotion, aiming to educate readers and build ethos. More informal external communication talks directly to the audience, engages readers with slang, varied punctuation and structure, and pathos appeals.
