"She said yes" -- Liminality and Engagement Announcements on Twitter

Social media sites enable people to share milestones in their lives, but relatively little is understood about how and why they are used in the context of major life changes. We utilize social media as a lens to explore the behavior of individuals undergoing a major life transition – those who use Twitter to announce that they are engaged to be married. Inspired by the anthropological concept “liminality”, we identify behavior manifested in Twitter that characterize this transitional phase. A large-scale quantitative study of Twitter postings of engaged individuals spanning two years shows that this phase marks notable changes in behavior that can be gleaned from social media. A follow-up survey provides qualitative explanations for the statistical analysis. Our findings reveal how individuals may be utilizing social media in the context of a major milestone in life, and bear implications for social media design and applications.
