This article suggests that one of the understudied and substantive ways in which actors produce and transform social hierarchies and classifications is by aligning and misaligning genres. Alignments within and across genres have furnished methods for construing and evaluating qualities of people – as examples, the genre repertoires of job applications or promotion dossiers. A fine attunement to new and emergent semiotic alignments via genres can also reveal how people are engaging with social and technological transformations. To study this, we advocate turning to four focal points: shifting genre hierarchies, stabilizing genres, cross-genre identities, and empty genres.
