Since the article in question isn't showing up for me, I'll have to go on what I've seen other posters say.
My opinion is that there are certain people for whom this surgery is right. It is NOT a cosmetic procedure, since the end result is hardly any more attractive than the beginning (large scars and excess skin are common).
However, for certain people for whom the risks of the surgery are outweighed by the risks of their current state, then it's truly a blessing. People (especially older people who may be less able to exercise) with severe weight problems who have tried all other methods can often benefit from this surgery. It will get the weight off quickly, and can save a life. It WON'T make you into a supermodel.
I have a lot of sympathy for people with weight problems, since I graduted high school at 5' 9", 300 pounds (and I'm still a rather big guy). And, I used to think that surgeries like this were the answer (along with fad diets). However, I've since realized that in my case (and for most people this is true), the reason for the weight gain is a lack of self-control, and therefore the way to lose the weight is self-control. I was able to lose 65 pounds in about 1 year, and it's really made me realize that only the individual can be held responsible for their well-being, especially as far as weight is concerned (in most cases).
That's just my $.02, though.
