Social networks are so used because they allow people to connect and interact with others regardless of geographical distance.
They offer a variety of features and functionality, such as photo and video sharing, instant messaging, live streaming, and the ability to follow people and interests that interest you.
Social media is also a convenient way to stay informed about what's going on in the world and in the lives of people you know.
Furthermore, social networks have become an important platform for marketing and advertising, allowing companies to efficiently reach a global audience.
