The Obama article explains how Obama used online networking to help him in his campaign and fund-raising efforts. The article explains how he raised $55 million in one month just from his website. His website, mybarackobama.com helped him tremendously in his campaigning efforts, and was key to his success as a presidential candidate. The article continues on saying how more people now than ever have access to the web and to social networking sites.
The second life article is about a multiplayer online game that allows people to basically have a "second life" online. On second life you can do whatever you usually do, just online. It allows for people with disabilities to be able to socialize and communicate, without having to worry about our disability. It allows for people to build whatever they want, drive whatever car they want and much more. However, second life has been used more and more for abused children as a way to teach them social skills. I feel that second life can be very beneficial if used to help abused to children, however, I also feel that people without disabilities should have no need for such a thing.
