We launched the new design back in September, plus we added a couple of backend improvements. One really big improvement was the mass product uploader. Making updating and loading in new products easy breezy. The site was redesigned using Ruby on Rails version 3 with a mysql database backend. We are still tweaking it a little bit. Developing with a framework like rails makes my job as a programmer pretty easy. "Rails just make sense." Really I should say "Ruby just make sense."
