Basics
In general, social networking services allow users to create a profile for themselves, and can be broken down into two broad categories: internal social networking (ISN) and external social networking (ESN) sites, such as Orkut, MySpace, Facebook and Bebo. Both types can increase the feeling of community among people. An ISN is a closed/private community that consists of a group of people within a company, association, society, education provider and organization or even an "invite only" group created by a user in an ESN. An ESN is open/public and available to all web users to communicate and are designed to attract advertisers. ESN's can be smaller specialised communities (i.e. linked by a single common interest e.g TheSocialGolfer, ACountryLife.Com, Great Cooks Community) or they can be large generic social networking sites (e.g MySpace, Facebook etc).
However, whether specialised or generic there is commonality across the general approach of social networking sites. Users can upload a picture of themselves, create their 'profile' and can often be "friends" with other users. In most social networking services, both users must confirm that they are friends before they are linked. For example, if Rosie lists Jim as a friend, then Jim would have to approve Rosie's friend request before they are listed as friends. Some social networking sites have a "favorites" feature that does not need approval from the other user. Social networks usually have privacy controls that allows the user to choose who can view their profile or contact them, etc.
Some social networking sites are created for the benefits of others, such as parents social networking site "Gurgle". This website is for parents to talk about pregnancy, birth and bringing up children. Several social networks in Asian markets such as India, China, Japan and Korea have reached not only a high usage but also a high level of profitability. Services such as QQ (China), Mixi (Japan), Cyworld (Korea) or the mobile-focused service Mobile Game Town by the company DeNA in Japan (which has over 10 million users) are all profitable, setting them apart from their western counterparts.
Social Status
The social status of an individual is revealed on social networks. Sociologist Erving Goffman refers to the “Interaction Order” which he claims is the “part of the social life where face-to-face and spoken interactions occur” (Rhiengold: 2002, P171). He believes that the way people represent themselves provides other users information about them they want others to believe, while concealing the rest. Goffman believes that people also give off “information leaking true but uncontrolled information along with their more deliberate performances” (Rheingold: 2002, P171). Through social networks people are now able to completely control the information provided about themselves through the photos they include, the information provided, whether it be true or false and the friends they make. People are therefore now able to control their personal information and their desired social status.
Additional Features
Some social networks have additional features, such as the ability to create groups that share common interests or affiliations, upload or stream live videos, and hold discussions in forums. Geo-social networking co-opts internet mapping services to organize user participation around geographic features and their attributes.
There is also a trend for more interoperability between social networks led by technologies such as OpenID and OpenSocial.
Lately, mobile social networking has become popular. In most mobile communities, mobile phone users can now create their own profiles, make friends, participate in chat rooms, create chat rooms, hold private conversations, share photos and videos, and share blogs by using their mobile phone. Mobile phone users are basically open to every option that someone sitting on the computer has. Some companies provide wireless services which allow their customers to build their own mobile community and brand it, but one of the most popular wireless services for social networking in the UK is Facebook Mobile. Other companies provide new innovative features which extend the social networking experience into the real world.
Business model
Few social networks currently charge money for membership. In part, this may be because social networking is a relatively new service, and the value of using them has not been firmly established in customers' minds. Companies such as MySpace and Facebook sell online advertising on their site. Hence, they are seeking large memberships, and charging for membership would be counterproductive. Some believe that the deeper information that the sites have on each user will allow much better targeted advertising than any other site can currently provide.
Social networks operate under an autonomous business model, in which a social network's members serve dual roles as both the suppliers and the consumers of content. This is in contrast to a traditional business model, where the suppliers and consumers are distinct agents. Revenue is typically gained in the autonomous business model via advertisements, but subscription-based revenue is possible when membership and content levels are sufficiently high.
