One thing that I would change are the "guarding of" references. I originally used them as a means of trying to convey their social roles more clearly, but after some further scrutiny I decided against in and instead went with "ing" at the end of the exertion role.

We socionics enthusiasts could use a program -- a PHP script, perhaps -- that can calculate relations, quadras, etc. just by putting in a type. That would definitely be more helpful for beginners than an exhaustive list.
