I 100% disagree... I found it to be extremely accurate. Like Scary Accurate.
A basic problem with this kinds of tests is that it's too easy to interpret the results to fit a very wide range of personalities - just like a horoscope will fit just about everyone who believes in them.
But they're still fun, and might give a hint about some general tendencies.

So no, not scary accurate like a horoscope. :)
There's also the aspect of giving the "right" answers to achieve a desired result. It's not very difficult to e.g. get an inrovert or extrovert type, and everyone knows that "real" hackers are introvert, so...
Basically it's not science, definitely not in this form.
[edit: I would have expected more extroverts in the results here, since the target audience is entrepreneurial hackers. Maybe it's the proggit exodus that's showing?]
My point was that the constant claims that these categorisations were qualitatively indistinguishable from the zodiac are patently false, and there's the evidence.
"You have a need for other people to like and admire you, and yet you tend to be critical of yourself. While you have some personality weaknesses you are generally able to compensate for them. You have considerable unused capacity that you have not turned to your advantage. Disciplined and self-controlled on the outside, you tend to be worrisome and insecure on the inside. At times you have serious doubts as to whether you have made the right decision or done the right thing. You prefer a certain amount of change and variety and become dissatisfied when hemmed in by restrictions and limitations. You also pride yourself as an independent thinker; and do not accept others' statements without satisfactory proof. But you have found it unwise to be too frank in revealing yourself to others. At times you are extroverted, affable, and sociable, while at other times you are introverted, wary, and reserved. Some of your aspirations tend to be rather unrealistic."
