Every social network serves its own purpose. YouTube lets you share videos. Instagram lets you share pictures. Tumblr lets you blog.
Two social networks are truly everywhere: Facebook and Twitter. However, they serve very different purposes.
- Facebook lets you keep in touch with a few people you already know in real life.
- Twitter lets you connect with many people you don’t know based on common interests.
Twitter is a group conversation, a giant, real-time chatroom. People connect around their interests: sports, celebrities, news, technology, and business.
Twitter’s following structure makes it “opt-in,” a lot like an RSS feed. Users choose to follow content and people they care about. Other people choosing to follow you is a key component to getting your voice heard.
