Public Writing definition

To me, the definition of public writing is what it sounds like; writing for the public. So that could be anything from an advertisement to a public speech. A speech that the President delivers could be public writing. An advertisement for Colgate could be public writing. Public writing is a message that someone expresses through writing and is revealed publicly. It's writing that the author wants the public to see or hear so it's done on purpose. It's writing that's done for a reason. In order to gain a large public audience (which is probably ideal for the public writing author), the message may have to appeal to large amount races, religions, ethnic groups, and both genders. Public writing must be clear, concise, and simple to a certain degree.
