Prismatic releases API for interest tagging, in free beta to all developers

I like prismatic for its design, strong engineering mindset and Bradford Cross. But I don't understand prismatic's goal. Are they trying to become feedly/newsblur? Or they they want to create this taste graphs for users?

What is the core problem they are trying to solve? Or just building out cool technology and setting themselves up for an acquisition/acquihire by a media company like Yahoo? How are they planning to make money?

Simple Perl interface to this API is now on CPAN: https://metacpan.org/pod/WebService::Prismatic::InterestGrap...
