Frugal Fad?

I was reading an article the other day saying how frugality is a popular fad right now, apparently frugal is the new black. The author was saying that as soon as the economy starts looking up people will be back to their old ways.
First I thought, what the heck are they talking about? I don't see people really becoming frugal. The people who were frugal before are still and the people out using credit to buy things they can't afford are still at their old ways (with a few exceptions).
Then I thought about my own life. First off, I have only been an extreme shopper (that is what the media is calling people who shop like I do) for about 6 months. We used to buy things on credit but I thought we were doing fine, after all we could always make the payments. Then we took a Dave Ramsey class and it changed our lives. We got so sick of being in debt and realized how stupid it was. My whole outlook on money has changed. I am frugal so I can save more and give more. It has nothing to do with the economy being down.
I don't think I'll ever go back to my old ways. There may be times when I don't coupon with such intensity or times we spurge on something (always with cash, of course) but on a whole I love our new financial life. We have such freedom. I don't feel deprived, I feel in control of our money. I have peace about or future (since we are saving for it now). I don't worry about how we will pay the mortgage next month. I don't wonder where the money went. We tell our money where to go, based on what we value in life.
So what about you? Do you live frugally? What has caused you to? Do you think you will stick with these habits?
