That's a good idea. I'll write a postmortem after the fact, but right now I'm busy reverting the site to its former state. Conversions dropped ~75%, so it's beyond the point where its practical to tweak the design in order to get it back to par. The entire goal was to increase conversions. It didn't. Rewind.
Please do write that postmortem. I'm very interested in the subject of older designs that are more popular than the ones using the latest & supposedly greatest tools.
