The social web is a set of social relations that link people through the World Wide Web. The Social web encompasses how websites and software are designed and developed in order to support and foster social interaction. These online social interactions form the basis of much online activity including online shopping, education, gaming and social networking websites. The social aspect of Web 2.0 communication has been to facilitate interaction between people with similar tastes. These tastes vary depending on who the target audience is, and what they are looking for. For individuals working in the public relation department, the job is consistently changing and the impact is coming from the social web. The influence, held by the social network is large and ever changing.
As people's activities on the Web and communication increase, information about their social relationships become more available. Social networking sites such as MySpace and Facebook, as well as the future Dataweb enable people and organizations to contact each other with persistent human-friendly names.
Today hundreds of millions of Internet users are using thousands of social websites to stay connected with their friends, discover new friends, and to share user-created content, such as photos, videos, social bookmarks, and blogs, even through mobile platform support for cell phones.
By the end quarter in 2008, Facebook reported 67 million members, MySpace occupied 100 million users, and YouTube had more than 100 million videos and 2.9 million user channels, and these numbers are consistently growing. The social Web is quickly reinventing itself, moving beyond simple web applications that connect individuals to become an entirely new way of life.
Both blogs and Wikis are prime examples of collaboration through the Internet, a feature of the group interaction that characterizes the social Web. Blogs are used as BBS for the 21st century on which people can post discussions, whereas Wikis are constructed and edited by anyone who is granted access to them. Members of both are able to see the recent discussions and changes made, although for many blogs and Wikis such as Wikipedia this is true even for non-members. Blogs and Wikis allow users to share information and educate one another, and these social interaction are focused on content and meaning. Blogs and Wikis are used by both those writing them and those who reference them as resources. Blogs allow members to share ideas and other members to comment on those ideas, while Wikis facilitate group collaboration: both of these tools open a gateway of communication in which social interaction allows the web to develop. These sites are used by teachers and students alike to accomplish the goal of sharing education, and working in a community with other scholars enables the users to see different interpretations of similar subjects as well as to share resources that might not be available to them otherwise.
