Great article, mainly for the author's Snakes On A Plane reference, but the other material was good too.
...clearly I have nothing to add to this. Plenty of excellent posts by several members already!
edit: Actually, I will say that I appreciate the author's nuanced approach. He wrote an article about calories mattering (more so in his opinion than any other factor in fat loss) but as he did so he maintained the perspective that quality of food is the most important dietary determinant of health. In his words: "Eating wholesome, minimally processed, nutrient-dense foods is the best way to ensure good health."
Personally, I think good health trumps everything (and leads to everything... like fat loss). As long as people aim for excellent health first (which from the dietary aspect means eating quality, nutritious food), then I think it can be very useful to start counting calories as a strategy to lose weight (if they so desire). Health first, calorie counting second -- don't skip step 1.
