I took this again just now out of curiosity, and there seem to have been some changes made to the test. The question Bloomsby complained about is gone, as is one question I alluded to, and I don't know how many other adjustments have been made. (Still no "maybe" option though).
My first result changed a little (within the margin of error), but my second result changed significantly- I'm not sure how much of this was due to changes in my views and how much can be blamed on changes made to the test.
