Vernacular is more in conjunction with discourse community in that they speak in a certain way that relates to where they live and how they interact. Everyday writing is more of a way to write not based on words used to interact. Everyday writing is more based on why and how you write. They are similar in that certain vernacular can but used in everyday writing depending on the audience and who the rhetoric is writing for. Tombstones are more of a vernacular because it's not everyday that someone dies. The words used on tombstones are specific for the time being and related to the person buried there.
