For clarity, the first is a NYT article about the profile that is generated by the second website, and the third is the actual research that was used to build the program. 

I'm relatively conflicted about whether I should consider this an entertaining novelty or a legitimate marker of how data can be used.  It's relatively obvious at this point that entities of all sorts, from the government to advertisers and corporations, compile, analyze, and subsequently utilize data.  It's a question of personal interpretation as to whether or not this is nefarious, useful, or somewhere in between. 

In the context of this application, I'm loath to admit that a machine can easily categorize me based upon what I've posted to my Facebook over the last eight years.  But the fact of that matter is that it still did a fair job:  I'm a Marine and a business school student, but it still pegged my closest match as Andy Warhol.  Given that I'm a photographer and have an Art History degree, it managed to smoke me out all the same.  For the record, Warhol was a terrible force in the history of art and culture.
