Previous Scholarship

Scholarship concerning SNSs is emerging from diverse disciplinary and methodological traditions, addresses a range of topics, and builds on a large body of CMC research. The goal of this section is to survey research that is directly concerned with social network sites, and in so doing, to set the stage for the articles in this special issue. To date, the bulk of SNS research has focused on impression management and friendship performance, networks and network structure, online/offline connections, and privacy issues.

Impression Management and Friendship Performance

Like other online contexts in which individuals are consciously able to construct an online representation of self—such as online dating profiles and MUDS—SNSs constitute an important research context for scholars investigating processes of impression management, self-presentation, and friendship performance. In one of the earliest academic articles on SNSs, boyd (2004) examined Friendster as a locus of publicly articulated social networks that allowed users to negotiate presentations of self and connect with others. Donath and boyd (2004) extended this to suggest that "public displays of connection" serve as important identity signals that help people navigate the networked social world, in that an extended network may serve to validate identity information presented in profiles.

While most sites encourage users to construct accurate representations of themselves, participants do this to varying degrees. Marwick (2005) found that users on three different SNSs had complex strategies for negotiating the rigidity of a prescribed "authentic" profile, while boyd (in press-b) examined the phenomenon of "Fakesters" and argued that profiles could never be "real." The extent to which portraits are authentic or playful varies across sites; both social and technological forces shape user practices. Skog (2005) found that the status feature on LunarStorm strongly influenced how people behaved and what they choose to reveal—profiles there indicate one's status as measured by activity (e.g., sending messages) and indicators of authenticity (e.g., using a "real" photo instead of a drawing).

Another aspect of self-presentation is the articulation of friendship links, which serve as identity markers for the profile owner. Impression management is one of the reasons given by Friendster users for choosing particular friends (Donath & boyd, 2004). Recognizing this, Zinman and Donath (2007) noted that MySpace spammers leverage people's willingness to connect to interesting people to find targets for their spam.

In their examination of LiveJournal "friendship," Fono and Raynes-Goldie (2006) described users' understandings regarding public displays of connections and how the Friending function can operate as a catalyst for social drama. In listing user motivations for Friending, boyd (2006a) points out that "Friends" on SNSs are not the same as "friends" in the everyday sense; instead, Friends provide context by offering users an imagined audience to guide behavioral norms. Other work in this area has examined the use of Friendster Testimonials as self-presentational devices (boyd & Heer, 2006) and the extent to which the attractiveness of one's Friends (as indicated by Facebook's "Wall" feature) impacts impression formation (Walther, Van Der Heide, Kim, & Westerman, in press).

Networks and Network Structure

Social network sites also provide rich sources of naturalistic behavioral data. Profile and linkage data from SNSs can be gathered either through the use of automated collection techniques or through datasets provided directly from the company, enabling network analysis researchers to explore large-scale patterns of friending, usage, and other visible indicators (Hogan, in press), and continuing an analysis trend that started with examinations of blogs and other websites. For instance, Golder, Wilkinson, and Huberman (2007) examined an anonymized dataset consisting of 362 million messages exchanged by over four million Facebook users for insight into Friending and messaging activities. Lampe, Ellison, and Steinfield (2007) explored the relationship between profile elements and number of Facebook friends, finding that profile fields that reduce transaction costs and are harder to falsify are most likely to be associated with larger number of friendship links. These kinds of data also lend themselves well to analysis through network visualization (Adamic, Büyükkökten, & Adar, 2003; Heer & boyd, 2005; Paolillo & Wright, 2005).

SNS researchers have also studied the network structure of Friendship. Analyzing the roles people played in the growth of Flickr and Yahoo! 360's networks, Kumar, Novak, and Tomkins (2006) argued that there are passive members, inviters, and linkers "who fully participate in the social evolution of the network" (p. 1). Scholarship concerning LiveJournal's network has included a Friendship classification scheme (Hsu, Lancaster, Paradesi, & Weniger, 2007), an analysis of the role of language in the topology of Friendship (Herring et al., 2007), research into the importance of geography in Friending (Liben-Nowell, Novak, Kumar, Raghavan, & Tomkins, 2005), and studies on what motivates people to join particular communities (Backstrom, Huttenlocher, Kleinberg, & Lan, 2006). Based on Orkut data, Spertus, Sahami, and Büyükkökten (2005) identified a topology of users through their membership in certain communities; they suggest that sites can use this to recommend additional communities of interest to users. Finally, Liu, Maes, and Davenport (2006) argued that Friend connections are not the only network structure worth investigating. They examined the ways in which the performance of tastes (favorite music, books, film, etc.) constitutes an alternate network structure, which they call a "taste fabric."

Bridging Online and Offline Social Networks

Although exceptions exist, the available research suggests that most SNSs primarily support pre-existing social relations. Ellison, Steinfield, and Lampe (2007) suggest that Facebook is used to maintain existing offline relationships or solidify offline connections, as opposed to meeting new people. These relationships may be weak ties, but typically there is some common offline element among individuals who friend one another, such as a shared class at school. This is one of the chief dimensions that differentiate SNSs from earlier forms of public CMC such as newsgroups (Ellison et al., 2007). Research in this vein has investigated how online interactions interface with offline ones. For instance, Lampe, Ellison, and Steinfield (2006) found that Facebook users engage in "searching" for people with whom they have an offline connection more than they "browse" for complete strangers to meet. Likewise, Pew research found that 91% of U.S. teens who use SNSs do so to connect with friends (Lenhart & Madden, 2007).

Given that SNSs enable individuals to connect with one another, it is not surprising that they have become deeply embedded in user's lives. In Korea, Cyworld has become an integral part of everyday life—Choi (2006) found that 85% of that study's respondents "listed the maintenance and reinforcement of pre-existing social networks as their main motive for Cyworld use" (p. 181). Likewise, boyd (2008) argues that MySpace and Facebook enable U.S. youth to socialize with their friends even when they are unable to gather in unmediated situations; she argues that SNSs are "networked publics" that support sociability, just as unmediated public spaces do.

Privacy

Popular press coverage of SNSs has emphasized potential privacy concerns, primarily concerning the safety of younger users (George, 2006; Kornblum & Marklein, 2006). Researchers have investigated the potential threats to privacy associated with SNSs. In one of the first academic studies of privacy and SNSs, Gross and Acquisti (2005) analyzed 4,000 Carnegie Mellon University Facebook profiles and outlined the potential threats to privacy contained in the personal information included on the site by students, such as the potential ability to reconstruct users' social security numbers using information often found in profiles, such as hometown and date of birth.

Acquisti and Gross (2006) argue that there is often a disconnect between students' desire to protect privacy and their behaviors, a theme that is also explored in Stutzman's (2006) survey of Facebook users and Barnes's (2006) description of the "privacy paradox" that occurs when teens are not aware of the public nature of the Internet. In analyzing trust on social network sites, Dwyer, Hiltz, and Passerini (2007) argued that trust and usage goals may affect what people are willing to share—Facebook users expressed greater trust in Facebook than MySpace users did in MySpace and thus were more willing to share information on the site.

In another study examining security issues and SNSs, Jagatic, Johnson, Jakobsson, and Menczer (2007) used freely accessible profile data from SNSs to craft a "phishing" scheme that appeared to originate from a friend on the network; their targets were much more likely to give away information to this "friend" than to a perceived stranger. Survey data offer a more optimistic perspective on the issue, suggesting that teens are aware of potential privacy threats online and that many are proactive about taking steps to minimize certain potential risks. Pew found that 55% of online teens have profiles, 66% of whom report that their profile is not visible to all Internet users (Lenhart & Madden, 2007). Of the teens with completely open profiles, 46% reported including at least some false information.

Privacy is also implicated in users' ability to control impressions and manage social contexts. Boyd (in press-a) asserted that Facebook's introduction of the "News Feed" feature disrupted students' sense of control, even though data exposed through the feed were previously accessible. Preibusch, Hoser, Gürses, and Berendt (2007) argued that the privacy options offered by SNSs do not provide users with the flexibility they need to handle conflicts with Friends who have different conceptions of privacy; they suggest a framework for privacy in SNSs that they believe would help resolve these conflicts.

SNSs are also challenging legal conceptions of privacy. Hodge (2006) argued that the fourth amendment to the U.S. Constitution and legal decisions concerning privacy are not equipped to address social network sites. For example, do police officers have the right to access content posted to Facebook without a warrant? The legality of this hinges on users' expectation of privacy and whether or not Facebook profiles are considered public or private.

Other Research

In addition to the themes identified above, a growing body of scholarship addresses other aspects of SNSs, their users, and the practices they enable. For example, scholarship on the ways in which race and ethnicity (Byrne, in press; Gajjala, 2007), religion (Nyland & Near, 2007), gender (Geidner, Flook, & Bell, 2007; Hjorth & Kim, 2005), and sexuality connect to, are affected by, and are enacted in social network sites raise interesting questions about how identity is shaped within these sites. Fragoso (2006) examined the role of national identity in SNS use through an investigation into the "Brazilian invasion" of Orkut and the resulting culture clash between Brazilians and Americans on the site. Other scholars are beginning to do cross-cultural comparisons of SNS use—Hjorth and Yuji (in press) compare Japanese usage of Mixi and Korean usage of Cyworld, while Herring et al. (2007) examine the practices of users who bridge different languages on LiveJournal—but more work in this area is needed.

Scholars are documenting the implications of SNS use with respect to schools, universities, and libraries. For example, scholarship has examined how students feel about having professors on Facebook (Hewitt & Forte, 2006) and how faculty participation affects student-professor relations (Mazer, Murphy, & Simonds, 2007). Charnigo and Barnett-Ellis (2007) found that librarians are overwhelmingly aware of Facebook and are against proposed U.S. legislation that would ban minors from accessing SNSs at libraries, but that most see SNSs as outside the purview of librarianship. Finally, challenging the view that there is nothing educational about SNSs, Perkel (in press) analyzed copy/paste practices on MySpace as a form of literacy involving social and technical skills.

This overview is not comprehensive due to space limitations and because much work on SNSs is still in the process of being published. Additionally, we have not included literature in languages other than English (e.g., Recuero, 2005 on social capital and Orkut), due to our own linguistic limitations.

Overview of This Special Theme Section

The articles in this section address a variety of social network sites—BlackPlanet, Cyworld, Dodgeball, Facebook, MySpace, and YouTube—from multiple theoretical and methodological angles, building on previous studies of SNSs and broader theoretical traditions within CMC research, including relationship maintenance and issues of identity, performance, privacy, self-presentation, and civic engagement.

These pieces collectively provide insight into some of the ways in which online and offline experiences are deeply entwined. Using a relational dialectics approach, Kyung-Hee Kim and Haejin Yun analyze how Cyworld supports both interpersonal relations and self-relation for Korean users. They trace the subtle ways in which deeply engrained cultural beliefs and activities are integrated into online communication and behaviors on Cyworld—the online context reinforces certain aspects of users' cultural expectations about relationship maintenance (e.g., the concept of reciprocity), while the unique affordances of Cyworld enable participants to overcome offline constraints. Dara Byrne uses content analysis to examine civic engagement in forums on BlackPlanet and finds that online discussions are still plagued with the problems offline activists have long encountered. Drawing on interview and observation data, Lee Humphreys investigates early adopters' practices involving Dodgeball, a mobile social network service. She looks at the ways in which networked communication is reshaping offline social geography.

Other articles in this collection illustrate how innovative research methods can elucidate patterns of behavior that would be indistinguishable otherwise. For instance, Hugo Liu examines participants' performance of tastes and interests by analyzing and modeling the preferences listed on over 127,000 MySpace profiles, resulting in unique "taste maps." Likewise, through survey data collected at a college with diverse students in the U.S., Eszter Hargittai illuminates usage patterns that would otherwise be masked. She finds that adoption of particular services correlates with individuals' race and parental education level.

Existing theory is deployed, challenged, and extended by the approaches adopted in the articles in this section. Judith Donath extends signaling theory to explain different tactics SNS users adopt to reduce social costs while managing trust and identity. She argues that the construction and maintenance of relations on SNSs is akin to "social grooming." Patricia Lange complicates traditional dichotomies between "public" and "private" by analyzing how YouTube participants blur these lines in their video-sharing practices.

The articles in this collection highlight the significance of social network sites in the lives of users and as a topic of research. Collectively, they show how networked practices mirror, support, and alter known everyday practices, especially with respect to how people present (and hide) aspects of themselves and connect with others. The fact that participation on social network sites leaves online traces offers unprecedented opportunities for researchers. The scholarship in this special theme section takes advantage of this affordance, resulting in work that helps explain practices online and offline, as well as those that blend the two environments.

Future Research

The work described above and included in this special theme section contributes to an on-going dialogue about the importance of social network sites, both for practitioners and researchers. Vast, uncharted waters still remain to be explored. Methodologically, SNS researchers' ability to make causal claims is limited by a lack of experimental or longitudinal studies. Although the situation is rapidly changing, scholars still have a limited understanding of who is and who is not using these sites, why, and for what purposes, especially outside the U.S. Such questions will require large-scale quantitative and qualitative research. Richer, ethnographic research on populations more difficult to access (including non-users) would further aid scholars' ability to understand the long-term implications of these tools. We hope that the work described here and included in this collection will help build a foundation for future investigations of these and other important issues surrounding social network sites.

Notes

1. To differentiate the articulated list of Friends on SNSs from the colloquial term "friends," we capitalize the former.
2. Although one out of seven teenagers received unwanted sexual solicitations online, only 9% came from people over the age of 25 (Wolak, Mitchell, & Finkelhor, 2006). Research suggests that popular narratives around sexual predators on SNSs are misleading—cases of unsuspecting teens being lured by sexual predators are rare (Finkelhor, Ybarra, Lenhart, boyd, & Lordan, 2007). Furthermore, only .08% of students surveyed by the National School Boards Association (2007) met someone in person from an online encounter without permission from a parent.
