As a designer, inventor, developer and entrepreneur who spends much of his time trying to improve user experience, I have to say I only noticed this "UX" label being used about a year ago. A few years ago there was HUI engineer, HI designer, interface designer, and cognitive scientist, all different names for the same job just like a job where you develop software might be called software engineer, developer, programmer, programmer analyst, architect, designer, etc. Now we have the term UX. I wonder what other labels there are floating about in the field of interface design. Until today reading this post I thought UX is just the hip new word for HUI. Now I find that HUI has been split into two different specialties. More and more people being added to each part of the task is not a good thing because the interface needs to be consistent and coherent, not broken into pieces each designed by a different group with a different philosophy. Oh sure there can be some document saying what the philosophy is supposed to be; but mission statements are not designs. The greatest interfaces I have seen there was exactly one person in charge of deciding how everything works and that was guided by his personal philosophy of design.
