I think the article could have benefited from having Ben's observations grafted onto more structured models of individual preference such as Myers Briggs Typology and the Merrill-Reid Four Quadrant Model, rather than having him create his own limited and incomplete model. I could compare this to someone trying to write for the first time without ever having been taught to write. So the person creates his/her own alphabet and starts writing. This alphabet seems great, so much more so because the person does not know anything about the other alphabets out there. But if we were to compare his alphabet with those that have benefited from hundreds of years of improvement by many different individuals, then we would see that his alphabet is quite incomplete, unexpressive and limiting. I think in much the same way the Ones / Twos "alphabet" is less expressive and much more limiting compared to existing preference models such as MBTI and the four quadrant models. Over many years, a lot of people have done a lot of work in order to create models that describe personal preferences -- so I think it would make sense to re-use rather than build from scratch. That is so much more true given that the other models look at more dimensions and have more categories and are thus able to categorize variability much more accurately.
