Boyd and Ellison ( 2007) defined social network sites as “ web-based services that allow individuals to (1) construct a public or semi-public 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”(2). Where as, Beer (2008) article was a response to Boyd and Ellison’s essay. Beer argued that to Boyd and Ellison definition of social network is too broad and it be more classified. Additionally, Beer suggested that Boyd and Ellison’s definition should be used as a base for categorizing different types of websites. Therefore, Beer suggested that “ in place of a very general vision of these sites as social network sites, why not use a term like Web 2.0 to describe the general shift and then fit categories, such as wiki’s , folksonomies, mashups and social networking sites within it”(5)
I strongly agree with Boyd and Ellison’s definition of the networking sites, and think that it is clear and valuable. However, unlike what Beer thinks of the networking definition, I do not think that Boyd and Ellison’s definition may cause misleading. Thu, I think that Beer’s suggestion of categorizing the networking definition to make it clearer and more precise is a valuable suggestion as well.
People may use social network to maintain old relationships (classmates, coworkers, friends, family members…so on), or look for new relationships within the social network system such as Facbook and Myspace. Therefore, in social network you would have unique connections with others and can not fake your identity because everyone knows you. However, people use online communities because they have a common interest that held them together such as a hobby, profession, national origin, religion, or similar lifestyle and so on. Online communities’ users may have pre-established interrelationships, but not necessarily, so they are mostly do not know anything about each others at all in which would make it easier for users to use a fake identity and not have a unique relationships because the connections within this system will overlaps. Also when conflict arises it would be harder to solve the problem within the system in online communities than the social network sites.
