I read it and thought it was great too.
But also agree that a lot of these traits can be on more of a sliding scale (or maybe more acurately, a bell curve? Who knows), so blanket statements often don't apply -- either blanket statements made about types, or about dichotomies.
For example, I find many of the S's on this site interesting, in that they do not reflect many of the S's I encounter irl. Both of my ISxJ parents scoff at mbti, and have no patience for any sort of winding theoretical discussions such as occur on this site. They're firmly in the 'real world', in the here and now, and reject (or smirk, lol) immediately any attempt to talk about personality theory.
With counter examples: I have several N friends who have never been the foruming types.. they are too busy with their lives and jobs and just don't spend (waste? lol) much time on the net; however, they are very receptive and interested in having these sorts of conversations.
So I think it's always important to remember that even this forum, and all its types, is rather a unique/specific demographic, that being a group of people who are specifically interested/'obsessed' with armchair personality theorizing, AND also forumers. I don't think it's necessarily representative of type trends - the full gamit, at least. (And I'm not directing this towards only S's - I mean, there have been several very unhealthy/unbalanced N's on this site as well. Oh no! The 'unhealthy' word being thrown around!
)
To add to shortnsweet's post/theme, for me at least I have always felt I have had to somehow insert myself and my views into a world that doesn't necessarily apply to them. People on the opposite extreme I would imagine would start out with the world as-is, and merrily & naturally insert themselves into that, and from there build views based on the reality. For myself, it has been very learned.... this concept of recognizing and accepting the world as-is, and as a given. And admittedly, my having been able to incorporate this learning has made me much happier / more balanced too. But it is always again something I have to remind myself of; it's not a natural cognitive step.
(And none of this is to say this isn't going to apply to some S's.)
