People use social networking sites for meeting new friends, finding old friends, or locating people who have the same problems or interests they have, called niche networking.
More and more relationships and friendships are being formed online and then carried to an offline setting.
Users do not necessarily share with others the content which is of most interest to them, but rather that which projects a good impression of themselves.
While everyone agrees that social networking has had a significant impact on social interaction, there remains a substantial disagreement as to whether the nature of this impact is completely positive.
Researchers have contended that this form of communication is an impoverished version of conventional face-to-face social interactions, and therefore produce negative outcomes such as loneliness and depression for users who rely on social networking entirely. By engaging solely in online communication, interactions between communities, families, and other social groups are weakened.
