In discussion of the papers in this special issue, we note that styling and crossing are not new phenomena, but are found world wide and are very old. This suggests that analyses of styling and crossing in comparative and historical perspective would be highly desirable. Such analysis will require rigorous macroanalytic characterizations of speakers and interlocutors in order to make comparison possible. The complex pragmatic effects of styling challenge both theory and method in pragmatics, but we will not fully understand what these challenges are until we attempt relatively formal analysis of these effects, which must include very large-scale phenomena such as domination and appropriation versus transgression and liberation.
