Facebook Live gets an audio-only mode. With this you can broadcast live with only audio message, this feature is really interesting and will be helpful to some group of people. This will be a good way of podcasting especially in Facebook.
In addition to the Audio live, I wish Facebook would enable and audio-only mode for streams which already include video. Sometimes I don’t need to see what’s happening in the actual video, as I am only be interested with what the streamers are saying. Not to mention that with Live audio, you’re able to keep sound going even as you leave the app or lock your phone if you’re on Android (iOS so long as you’re within the app). You can’t do that with video streams.
