Social networking /summary 1

Social networking sites enabled probably the greatest migration of people to the virtual world. People have a new opportunity to interact not only in real life, but also in cyberspace, where geographical and other physical barriers don't exist. I'm not saying this is a promising thing overall, some people are obviously overdoing it, but it's still useful for keeping in touch with people. Together with the implementation of feeds and streams which enable dynamic information, social networking could represent the biggest and most important component of Web 2.0, reshaping business, marketing, and politics and just being plain amazing.\
