How to Use Social Networking Sites for Beginners
Built on the social networks Open Graph (a collection of your preferences, likes, interests and activity on Facebook and from around the web), Facebook apps allow you to personalize and enhance your participation on the social network. They can add anything from games (FarmVille) to photo albums to quizzes to music (Spotify). Most of Facebook s apps come from outside developers that use Facebook s API. Many represent strong partnerships and add additional social layers, like Washington Post Social Reader and Foursquare.
Enabling each Facebook app means granting that app permission to access data on your profile and post on your behalf. This often means sharing on your Timeline how you interact with that app. For example, when you use the Spotify app, the company will share songs you listen to on your Timeline for your friends to see and interact with unless you choose to hide that activity. (Keep in mind many of these sharing options can be customized.)
A word of caution: Well made apps can add a fun and engaging layer to your Facebook experience, but using too many of them or requesting others to join might annoy your friends (and in the worst cases, compromise their privacy). You should only use apps recommended by friends you trust, or provided by reputable companies.
