Poll: What is your personality type?

I'd be very interested to know whether there was any correlation between HN readers and a specific trait of personality types.

If you don't know your type (Carl Jung's four letter system), there's a decent quiz here: http://www.16personalities.com/free-personality-test

I grew up with a member of my family who would often meet people and very quickly decide upon their personality type. As a result, I've always found it both fascinating and insightful. It'd be great to see the results on such a large yet focused group.
