I've taken a ton of these tests before; you're close, but I'm actually a pretty strongly expressed introvert (INTJ). Interesting that I would appear as an extrovert... I guess the situations where you guys don't see me are the ones that would change that perception, generic social situations I'm usually extremely quiet. Exilian has grown very organically around my own interests, and therefore I tend to be very "in my element" and actually have things to say here.
This variant of the test is interesting for the practice of giving percentage levels, which give a spurious an unwarranted level of claimed accuracy but do have the plus side of showing strong and weak expression of traits. I know some people who feel they fit the Myers-Briggs categories very well and others (perhaps whose expressions are more borderline) who feel that the categorisation system is poor. I tend to think of it as a fun test, but I'm sceptical of the idea it can be applied really broadly, not least because a lot of people have large shifts in their personality. Someone's basic "type" on these tests for example could easily change if they had certain symptoms of depression, and people change the habits being asked about and measured a lot over the course of their lives in many cases.
My scores from this variant of the test:
INTJ
Introvert(78%) iNtuitive(88%) Thinking(25%) Judging(67%)
You have strong preference of Introversion over Extraversion (78%)
You have strong preference of Intuition over Sensing (88%)
You have moderate preference of Thinking over Feeling (25%)
You have distinctive preference of Judging over Perceiving (67%)
