I'm pretty sure the timeline wouldn't work though. People wouldn't recognise you from the show because the show wouldn't broadcast for long after they shoot it. I guess people in the second season could recognise you from the first one, which would be airing around the time they're shooting the second one, or something.
Anyways, sure there are some live-in relationships, but there are relationships with the people they don't live with, as well. Seems like it would require more cameras to show poly networks where every partner has their own place.
