Many either don't understand responsive web design or have never heard of it. Responsive web design is essentially one website which can work on many different screen sizes, instead of having one website for the desktop and one website for mobile/tablets. It looks to be the next phase in web design and it's being adopted quite rapidly with the explosion of mobile phones and tablets.
One or two of you have asked me if I would ever make UltraLinx responsive. I'm currently not looking to do it purely because under 5% of the sites visitors are on mobiles/tablets. Most of people who read UltraLinx, read it on RSS apps such as FLUD or Flipboard. When the time comes to redesign UltraLinx, I will definitely implement responsive web design then.
