DHH wrote a very interesting post about his view on Responsive Web Design. He says: By going with dedicated templates, we don’t have to include needless data or navigation that’s going to be hidden by the responsive rules. We have less variables to think about on the individual page. It’s just a simpler workflow where it’s easier to make changes without considering a smather of side effects. So the next time you’re marveling at a responsive design that’s able to make the best use of a 27” iMac at full screen and a fit neatly on a 3.5” iPhone as well, you might want to ask yourself why you’re trying to make one performer do so many tricks. I totally agree with his view. Being responsive should be secondary to being fast, maintainable, and beautiful.At the Guardian, Responsive Web Design has been sold as such a golden principle that we would not even try to serve different templates depending on what type of device our readers are visiting us.I wish we could try RESS or Responsive Delivery instead of building very complex responsive templates that become more and more fragile and slow down mobile performance.As I wrote a few weeks ago: RWD is not the answer, it is only part of it.
