Yes, I did take the Enneagram, and came out as a 6.  Parts of it do describe me, but the closest correlation between a 6 and a Myers-Briggs type is apparently ISTJ/ISFJ, which is about the exact opposite of how I come out, an ENTP.  So that is rather confusing.  The Enneagram result does give me something to think about though.  Maybe I am in flux.  :)
