This is funny because I'm totally a "cart watcher" and it's sort of the same thing. I think you can tell a lot about a person by what's in their cart at the grocery store and likewise I think someone's fridge speaks volumes.
That was a fun site...interesting how I saw food in bowls in the fridge that wasn't covered up...the food looked dried up. Is that the food addict in me or the green and that is wasteful part of me?
