Individuals change and adapt their behavior according to their social situation (e.g., transitioning from work to home). However, how does this shape shifting of self-presentations and identity translate into various online platforms? This exploratory study utilizes a novel and mixed methodological approach to better understand user behavior across social media platforms. We interviewed 22 participants and employed a repertory grid technique to reveal deeper similarities and differences in behavior across various online platforms. We found that users had a variety of strategies for managing multiple audiences across multiple platforms. Almost all participants actively separated their professional (e.g., LinkedIn) and social (e.g., Facebook or Instagram) oriented platforms typically by self-censorship of posts rather than utilizing audience management tools. Via the repertory grid technique, we revealed a number of more subtle nuances of how participants reflect on how and why they maintain a number of social media identities.

个人根据自己的社会状况（例如，从工作过渡到家庭）改变并适应其行为。但是，自我表达和身份的这种形状转变如何转化为各种在线平台？这项探索性研究利用一种新颖的混合方法来更好地了解整个社交媒体平台上的用户行为。我们采访了22名参与者，并采用了储备库技术来揭示各种在线平台在行为上的更深相似之处和不同之处。我们发现用户有多种策略可以跨多个平台管理多个受众。几乎所有参与者都通常通过帖子的自我审查而不是利用受众管理工具来积极地分离面向专业（例如，LinkedIn）和社交（例如，Facebook或Instagram）的平台。通过库的网格技术，我们揭示了参与者如何反映他们如何以及为什么他们保持许多社交媒体身份的许多细微差别。
