The amazingly social social network.

Think of your most unique interest. If this interest is unique enough, chances are you don't know anyone who truly shares your passion for the subject. If you want to interact with those who share your interest of say, extreme geocaching, your options are really quite slim, but with the help of the internet, specifically social networks, other extreme geocachers like yourself can interact easily and share stories and helpful hints. This is one of the amazing implications of social networking, and one of Clay Shirky's points of interest in his book "Here Comes Everybody." Social networking has allowed for people with similar interests, no matter how obscure, to interact with great effectiveness. This social connectivity can foster all sorts of progress, such as disgruntled customers banding together in an effort to right a wrong caused by a corporation, or political activists joining together to speak with one strong voice. This powerful tool can also be used for evil as well, and it is up to us as users to moderate our actions as to promote good cooperation and progress.
