Matching people on, for example, the music and reading and what they pay attention to is the general idea at this time. They have a lot of very smart people working on this and I'm sure most of your concerns have been already dealt with, or at least identified. Fernando, Matchmine is not a personality testing system.

That would be another path to find content you might like." From http://www.matchmine.com/matchkey/matchkey2.php "How The MatchKey Works ..... MatchKey is a mathematical representation of your personal interests and tastes across a variety of media types. .... We start with a rich set of around 50 independent, mutually exclusive attributes that we call canonical axes." Oh, I HARDLY doubt because if they do not use directly a normative personality test, how the algorithm is going to manage DISTORTION? Profiling by music preferences, video preferences, color preferences, bookmarks preferences, handwriting analysis and more: Terrible lack of precision by distortion!!! See, for example: http://www.deweycolorsystem.com You can see the validation whitepaper at: http://www.deweycolorsystem.com/credentials/PDFS/DCS_23.pdf It is interesting to see how that color method used to evaluate personality ADDS DISTORTION to the measurement (page 07 and figure 2 continued of whitepaper) Also how the algorithm is going to compute the similarity of MatchKeys? I bet USD 10 cents the WHOLE precision is LESS than any person could achieve searching by his/her own!!! Which is the ensemble, precision and the equation to assess similarity of that algorithm?
