Writers in communities often write to specific audiences—a legislative representative, readers of a local newspaper, other members of a social group. With public writing, it is more likely that you are familiar with the views your readers hold and the assumptions they make, so you may be better able to judge how to engage those readers. If you are writing to a group of other parents about how to lower school bus transportation costs, for instance, you may know whether to lead by analyzing other school-related fees or by criticizing key decision makers.
