Well, Gary started it. He's apparently at work behind the scenes making something out this web fridge project - Here's Gary's Fridge, just before being eaten by its own trifle.
Farrago jumped in - Here's that catlover's Fridge.
And here's the Fishwrap's nicely appointed Fridge.
I can only add this. Our fridge is not nearly as neat and organized as these. I would not let any of you look inside. Just you wait, Gary, until Cameron is five and you have to hide everything good and adult on the top shelf, and her smeary hands decorate the empty shelves, until you give up and put everything in the freezer. You'll see.
The only other comment I have is that bloggers seem to use lots of condiments. There is as much to sprinkle and drink as to eat. That must mean something.
