Social networking allows people with similar interests to connect and share information online. The most popular social networks for personal interactions are Facebook, Google+, and Twitter. Social networking can help businesses gain contacts, clients, and awareness, even for small businesses. While social networking enables worldwide connectivity, sharing interests and information, and rapid information sharing, it also poses disadvantages like backlash, cyberbullying, risks of fraud and identity theft, wasting time, and lack of privacy as companies target users with advertisements.
