Self-presentation, the social process by which people reveal information about themselves and perform the social roles that structure everyday interactions, has been significantly altered by today's social technologies. Where Goffman's influential self-presentation framework focused on in-person, real-time role performances, today's technologies routinely involve viewing text and visual content aggregated over time and linked to an individual's persistent online identity, the capacity for both ephemeral and more permanent content, and novel modes of audience engagement such as liking and commenting. These new socio-technical affordances not only allow for novel behaviors, but also alter the temporal dynamics of the self-presentation process in ways that are not well understood. In this paper we address this gap through an interview study of 32 young gay and bisexual male (GBM) Instagram users in the United States. Results extend our understanding of the relationship between social technology affordances and the temporal dynamics of self-presentation. We show how participants drew on Instagram's affordances for identity persistence, content persistence and audience engagement to slow down or speed up their role performances to particular audiences, to increase the visibility of their performances without appearing overtly to seek attention, and to make their audience at any given point in time a part of the performance seen by future audiences.

自我展示是人们揭示自己的信息并履行构成日常互动的社会角色的社交过程，如今的社交技术已大大改变了自我展示。在戈夫曼颇具影响力的自我展示框架着重于面对面的实时角色表演的情况下，当今的技术通常涉及查看随时间推移而聚合的文本和视觉内容，并与个人的持续在线身份，短暂和永久内容的能力相关联，以及新颖的观众参与方式，例如喜欢和评论。这些新的社会技术能力不仅允许新颖的行为，而且还以一种人们不太了解的方式改变了自我表现过程的时间动态。在本文中，我们通过对32位美国年轻的男同性恋和双性恋（GBM）Instagram用户进行访谈研究来解决这一差距。结果扩展了我们对社会技术能力与自我表现的时间动态之间关系的理解。我们展示了参与者如何利用Instagram提供的身份持久性，内容持久性和观众参与度来减慢或加快其对特定观众的角色表演，增加其表演的知名度而又不会显得明显地引起人们的注意并使其观众在任何给定的时间点都是未来观众看到的表演的一部分。结果扩展了我们对社会技术能力与自我表现的时间动态之间关系的理解。我们展示了参与者如何利用Instagram提供的身份持久性，内容持久性和观众参与度来减慢或加快其对特定观众的角色表演，增加其表演的知名度而又不会明显地引起人们的注意并使其观众在任何给定的时间点都是未来观众看到的表演的一部分。结果扩展了我们对社会技术能力与自我表现的时间动态之间关系的理解。我们展示了参与者如何利用Instagram提供的身份持久性，内容持久性和观众参与度来减慢或加快其对特定观众的角色表演，增加其表演的知名度而又不会明显地引起人们的注意并使其观众在任何给定的时间点都是未来观众看到的表演的一部分。
