A similar genie began floating around blogs a number of years ago. Would say it's far from being absolute nonsense. Would also imagine numerous factors could contribute to development of alternative word choice. [without having looked at the algorithm or paper, neither of which are working for me] If I remember rightly, the previous test focused on use of specific contractions or generalisation, and references to self. Based on individual habits and inevitable variations it's easy to see how we can all become a bit 'confused'.
{Alright, having actually taken the test, it does admittedly seem even more simplistic than the last. Slightly disappointing in its limitations.}
