The rewrite of Discount Tire's website wasn't executed as a 'responsive' or 'adaptive' design. While those terms (particularly the the former), are starting to become ubiquitous today, when we started development nearly two years ago, they were a little more on the cutting edge. The concept felt right, ideal even, but there was very little industry experience with it. In fact, when I showed the demo I'd made to folks around the office, most had never seen anything like it.
Despite how simple and pure the concept seemed, executing it at the time seemed like a difficult balance. IE7 & IE8 accounted for the majority of our traffic, Javacript was turned off for about 3-4% of visitors (which at our volume is a lot of customers), and there were still some blackberries on the site at the time. I wanted to minimize transferred bytes for mobile visitors and we had to deliver a good experience for those non-js vistiors.
