As someone who has actually designed manufacturable boards I'd say the same. In addition the article has some strange recommendations:
* don't use QFN — I see no reason to, on the contrary, these are great packages (see my other post in this thread)
* 0603 minimum size for passives — huh? I see no reason not to go down to 0402, which is both easy to manufacture (assembly costs are the same, component costs are usually lower), and easy to prototype (just get a large desk magnifying glass and a good pair of tweezers and you're good to go).
