Facebook announced its new live streaming feature on its blog on August 6, 2015:
Starting today, public figures can share live video from Facebook Mentions, the app that makes it easy for athletes, musicians, politicians and other influencers to talk with their fans and each other. You can discover these live videos from public figures you follow in your News Feed. You can comment on, like or share the video while watching a live broadcast. You can also see when your friends or other public figures start watching.

This new live streaming feature on Facebook Mentions allows users to stay connected to their best celebs. However, one question lingers here:
Why should celebs be allowed to live stream on Facebook and we can’t? It doesn’t make any sense. Hence, this ‘feature’ needs to be revised.
