This sounds interesting. Also see the NYT article.
It reminds me of what I read about twenty years ago or so, AI researchers trying to build huge databases to give computers context of the natural world and the human social sphere. This idea, if it takes off, would harness the information and skills of millions of participants.
Furthermore, Google is trying to build an AI, and I'm sure the Google AI would be just as happy to slurp up the Freebase database as Freebase is to slurp up Wikipedia and other databases.
Folks, we are building God.
