With the addition of the “@” tag to Facebook status updates, Facebook takes another step in becoming more like Twitter. With the introduction of the news feed, Facebook used the general concept of Twitter, making your status updates visible, group-able and the ability to add media, such as links, pictures and videos.
The only upside to Twitter were mentions. The use of the “@” tag to highlight the user that you wanted to see the message, yet still allow the world to see it. This allows users to have public conversations, and let multiple people join the conversation.
Now Facebook is using tags to allow users to better communicate with each other. The “@” tag will allow users to directly post to a friend’s news feed or wall.
Facebook continues to emulate and improve on its competition, acquiring users of each platform that it gently nudges out of the way.
