This study examines identity presentations on the online social networking site, Facebook.com. The two-phase research design includes a period of participant observation of a sample of 346 college students and recent graduates followed by an interview period with a sample subset of 48 interviewees. The study analyzes key performance components on the site using a symbolic interaction perspective, to determine common characteristics of Facebook profiles, importance of performance components, and categories of identity performance. Identity performance components are broken into two general categories, static and dynamic. Dynamic components, those that are updated frequently and drive much of the activity online, are far more important in terms of identity performance. Dynamic components on Facebook found to be important in this study are status updates, use of bumper stickers and pieces of flair, giving gifts, and photos. Analysis of these components supports the symbolic interaction literature in general and the works of George H. Mead specifically. The Facebook news feed allows Facebookers to continually observe identity performances of others as well as to give and receive feedback on performances. This continual flow of information allows for the development of a generalized other, used as the basis for anticipating reactions from others to potential activity. Based on these anticipations, in an effort to reduce misinterpretations, Facebookers develop exaggerated performances that serve to distinguish in-groups from out-groups. knowing when to point the way, knowing when to let me find my own way, and, most importantly, maintaining calm through this whole process. Next, I'd like to thank the remainder of my committee, Mark Andrejevic, Dan Berkowitz, Frank Durham, Jane Singer, and Steve Wieting, for their great assistance throughout my years at Iowa, first in the classroom and later in helping me navigate the areas of my research. Lastly, I would like to thank everyone who has helped me along the way. This list is far too long to present here, but you know who you are. The kindness, friendship, and instruction offered by classmates, the J-School faculty and staff, faculty and staff outside the department, and everyone else whose path crossed with mine during my time at Iowa will not be forgotten. Thank you.
