The rise of social networking has been decried by several observers for decreasing sociability and actual face time. The fact is social websites provide a convenient and easy method to not only communicate with old friends but also make communications more personal. Instead of a letter once a month, it is possible to continue the relationship at the same level of intensity possible for next-door neighbors.
Of course, keeping old friends is only part of the picture. Many people have interests that are not shared by individuals in their geographic proximity. This is especially common in rural areas. Even in densely populated areas, it can be difficult to locate those who share your interests or hobbies. Social networking provides a solution to these problems, provided you are aware of the possibilities.
