Twitter is taking their new audio Spaces feature and picking up steam. There is currently development on a web version of Spaces that will let users join Spaces session through their desktop computers, and not just their phone or tablet apps.
This could be a real bonus for broadcasters since they will have access to all of their professional microphones and sound recording equipment that is only accessible on their workstations.
With the web version of Spaces, there will be more room to display the users in that Space.
