Social networking allows people to connect with others around the world and develop business opportunities. It has become a popular way to communicate in the 21st century. While searching information online has limitations, social networking links people together by connecting users to those with relevant knowledge and information. It is an excellent way to stay in touch with friends and family worldwide without meeting in person. Employers also use sites like LinkedIn to search for potential job candidates. Social networking helps create awareness of social issues and provides access to professional networking sites, blogs, documents, and presentations.
