They can.

What I mean is, that why we'll make this a mic-optional feed. If we want to hear what others are saying, we can listen in. If not, we put them on mute and watch. Either way, we'll all have the option of posting on a text chat (which doesn't interrupt anybody). Those who do have mics can mute everyone else out if they want to, but they'd still have the option of recording themselves as if they were alone.
This way we'll get the best commentary because everyone'd be in their comfort zone while watching.
