Social Network Sites: Definition, History, and Scholarship danah m. boyd, Nicole B. Ellison Journal of ComputerMediated Communication, Volume 13, Issue 1, pages 210–230, October 2021 Social Network Sites: Definition We define social work sites as webbased services that allow individuals to (1) construct a public or semipublic profile within a bounded system, (2) articulate a list of other users with whom they share a connection, and (3) view and traverse their list of connections and those made by others within the system. The nature and nomenclature of these connections may vary from site to site. While we use the term ―social work site‖ to describe this phenomenon, the term ―social working sites‖ also appears in public discourse, and the two terms are often used interchangeably. We chose not to employ the term ―working‖ for two reasons: emphasis and scope. ―Networking‖ emphasizes relationship initiation, often between strangers. While working is possible on these sites, it is not the primary practice on many of them, nor is it what differentiates them from other forms of putermediated munication (CMC). What makes social work sites unique is not that they allow individuals to meet strangers, but rather that they enable users to articulate and make visible their social works. This can result in connections between individuals that would not otherwise be made, but that is often not the goal, and these meetings are frequently between ―latent ties‖ (Haythornthwaite, 2021) who share some offline connection. On many of the large SNSs, participants are not necessarily ―working‖ or looking to meet new people。 instead, they are primarily municating with people who are already a part of their extended social work. To emphasize this articulated social work as a critical anizing feature of these sites, we label them ―social work sites.‖ While SNSs have implemented a wide variety of technical features, their backbone consists of visible profiles that display an articulated list of Friends1 who are also users of the system. Profiles are unique pages where one can ―type oneself into being‖ (Sund233。n, 2021, p. 3). After joining an SNS, an individual is asked to fill out forms containing a series of questions. The profile is generated using the answers to these questions, which typically include descriptors such as age, location, interests, and an ―about me‖ section. Most sites also encourage users to upload a profile photo. Some sites allow users to enhance their profiles by adding multimedia content or modifying their profile’s look and feel. Others, such as Facebook, allow users to add modules (―Applications‖) t
