The effects of technology on language and the effects of language on culture as a whole are profound and complex  The telegraph, the telephone, and the television have all changed the way people speak to one another  The best current example of such a change is the advent of electronic mail, which has effected a widespread loosening of language usage rules
This loosening has, in turn, made relationships between people more casual than ever before
A widespread loosening of overly rigid language-usage rules can improve communication.
