I wanted to mention here, too -- chaosrob started a thread today about another, somewhat similar test: General Social Chat > MBTI Jung typology. I already posted a link from that thread to this one.

It gave five choices per question instead of two, I felt more at home with the questions, and even though there was a tie in the results I liked both of my possibilities (ISTP, "Engineer" and ISFP, "Artist") better than the INTJ I got here. I also think it's funny that by now I've scored on both sides of N/S, F/T, and P/J -- been everyplace but E!

Doctora, the results you reposted in this thread are from that test too, aren't they?
