I did read the article, although it was very difficult to follow due to the way it was written. The point of my comment relates to the discussion of "tweakpoints' the article refers to at the end actually. Only tweaking particular parts to get it to work as opposed to rethinking how something works. I can almost guarantee you can't build a site that won't require the use of; 768px (sometimes), 480px and 320px media query rules to help tweak your layout, these are the problem widths hence the need to use media queries. There are two types of "responsive design" one is adaptive where the site only changes at particular breakpoints but can look horrible inbetween and "fluid responsive" where the site will continually scale down and you set a few breakpoints to make things look nicely.
