Social networking is an Internet phenomenon that allows users to connect and interact with friends, colleagues, or anyone with a shared interest. These sites can simplify communication over vast geographical boundaries, or as is the case on college campuses, very small ones. Another feature of the social networking sites is that they allow users to craft their own profiles, or public persona, for anonymous browsers to view. Formerly, one would need knowledge of web design to create a personal information page, but social networking makes the process easy. Users can make their own profiles private, but usually at least a picture is available to strangers.
