“Such communities tend to be small and isolated, such as those existing in mountain villages, or on small islands, or in desert oases. In some contrast, the former is a largely heterogeneous, socio-rhetorical assemblage of people who broadly share occupational or recreational experiences, goals, and interests.” Discourse communities can exist within small isolated communities as well as in large metropolitan areas.

“In consequence, when a university becomes established in a town, the presence of this constellation of discourse communities influences the wider urban environment; as a result, the urban environment provides services that are helpful to the university, such as cheap student housing, cheap restaurants, museums, and more bookshops, which in turn further consolidates our sense of a university town like Cambridge, Heidelberg, or Uppsala.” The benefits of being in discourse communites is that they can influence the surrounding areas that they are a part of.
