When we hear the word genre we think of books and music but discourse communities use genre also. The way they use genre depends of the type of community it is and discourse communities have their own language. Each discourse community will use certain words in a way that applies to that group only. This use of language is a type of social behavior. Since each communities has their own way of speaking and writing, you could be considered literate in one community and not literate at all in another community. Since there is no set standard for discourse communities, the term literate can not be easily applied here.
