Good summary.
I've known about it for awhile but only decided to take the test recently - ironically only because Bhagpuss just posted his less that positive view on it. Still, I enjoy silly things like this - though I do wonder what category gold farmer robots would fall under. Is there a fifth hidden type, "the enemy of man" or something?
Close enough, it even comes with some feel good text.
While it's probably just as trivial as the "which DBZ character are you!?" test I think it would be interesting to see what everyone else (at least those that comment here) got too, if you're willing to share? :)
