3.1 Facebook

Facebook is one of the best-known social networks. It allows you to publish and share news, create pages around a topic and create events. Publishing can be restricted to a circle of friends, or you can choose to publish publicly. Every piece of content can be "liked". The network is created "symmetrically": when you subscribe to someone, they also subscribe to your content. You can also choose to create a Facebook page. In this case, to follow your activity, Internet users must subscribe to your page. This page can be limited to a predefined community if required.
