The line between what is and isn't a social networking site isn't always a clear one. Internet message boards, for instance, facilitate the creation of online communities, but they typically don't have the robust "friends list" features of a true social networking site. Some sites don't have social networking as their primary goal, but accomplish that function. Last.fm, for instance, is a way for users to track their music listening habits, rate songs and create their own custom stations of streaming music to listen to. Because users can also compare their tastes to those of other users, and create profiles and friends lists, it also acts as a social networking site.
There are two things that a website must have to be defined as a social networking site:
1). The ability for users to create their own personal profile pages, containing whatever information they want to share about themselves.
2). The ability for users to link to each other and create a list of "friends" or "contacts" who can view each other's profiles and share social networking information.
Many social networking sites offer capabilities far beyond the basics, often based on the specific type of networking the site caters to. For example, a business networking site might allow users to post resumes or references. A photo sharing site would most likely have advanced image galleries built in, plus ways to rate or discuss other people's photos. A music-focused site could allow users to automatically upload lists of songs they listen to on their media players. New applications are expanding the capabilities of social networking sites every day, giving us more opportunities to interact with them (and, some might argue, fewer opportunities to get away from them).
Why are some sites more popular than others, and why do some sites fade in popularity after a while? Anyone who can give you a definite answer to that question is well on the way to becoming a millionaire. Actually, site popularity is defined by many complex factors. It also varies among different populations -- some sites are more popular with younger users, while some that are not well-known in the United States are popular in other countries.
Sometimes a fade in popularity can be attributed to a new site with more or more useful features. Sometimes it revolves around social networks themselves. For instance, a single user or group of users with a lot of connections can make a switch to a new site and bring all their contacts with them. Since every "friend" has his or her own friends, the ripple effect can eventually become enormous. For example, while Friendster has experienced a decline in American users, it has become enormously popular in the Philippines. Friendster traced the shift to one west coast American user who had many contacts in the Philippines [source: Woodard Maderazo].
