Mentions is designed to be used by the likes of famous athletes, musicians, actors and then some for both communicating with followers but also to get a better understanding of how they are perceived on the world's largest social network.
Although it looks like another version of the News Feed (or even a simpler version of Paper) displaying status updates and shared updates, there is more opportunity for fostering engagement with Mentions than from the standard Facebook app.
For example, public figures can set up live Q&A sessions via Mentions, which sounds much simpler for the more than 1.28 billion users to communicate live with these celebrities than trying to follow along to a hashtag on Twitter.
Mentions is launching initially for verified public accounts in the United States, with more countries and other proflies to be added in the coming months. Public figures can download the iPhone app to request access.
