I'm on the fence here -- yes it's more responsible, but McD's decision is all about limiting choice and increasing profit margins by offering only smaller portions. If someone wants a supersize next year, they should be able to get it -- but I personall never did, even though it was available and was an extra 25c or whatever. I can't say I totally disagree with anyone who's posted so far.
forseti-6 you especially made some good points, and I liked those yogurt parfaits too.
Now I need to rant
In terms of eating smart and staying in shape, people don't seem to realize that Atkins and the South Beach Diet and all the trendy shit that comes out each year isn't necessarily the key to good health. If you are really concerned about your diet and fitness, learn to eat healthy, skip the supersize, and get off your ass and run around the block a few times. It's really not all that hard! Meanwhile places like my cafeteria are starting to offer bland specials and crappier food because of the latest fad. "Atkins Special -- Sandwich w/o the Bun." It's just a piece of plain manky ass meat, and a pickle. WTF is that!!! I can't even get a decent burger anymore!! AARRGH
I want a damn hoagie now.
