I like to listen while I'm doing work around the house, specifically as I'm mowing the lawn or shoveling the snow. So there's not a set time that I listen to the show.
I listen to the Podcast in my car via my ipod which was a gift from my family last Christmas. We - I make them listen too - listen when we have a trip of an hour or more so that we can listen to the whole thing at once. It has initiated lots of family debate and conversation as welll as laughs. It also most recently initiated them to bug me to change our upcoming ADR for Kouzzina!
I listen on my iPhone. I like to listen at work, if it comes out while I'm working I just listen on my phone via the RSS feed. Otherwise I'll listen the next day after downloading it from iTunes.
I listen to the podcast on my iphone. I listen to most while I am working night shifts, it really helps with passing the time by on a slow night. I also find myself occasionally listening while working out.
