A significant aspect of rising customer care discourse are corporate twitter apologies in reply to customer complaints. This study focuses on their distinctive constituents and bonding capacity as a form of image repair molded by Twitter's media affordances. Corporate twitter apologies are distinctive for their rather rare use of Explanations (as a kind of softening) and their comparatively broader use of Repair Offers (as a kind of corrective action), typically accompanied by follow up moves like imperatives and questions. They are also distinctive in their recurrent, in some measure formulaic practice of greetings and signatures which do not turn up in apologies posted by common Twitter members.
