I am already enjoying benefits of grouplization. Real-time traffic is monitored via millions of smart phone GPS and Inertial sensors. The data (may or may not be satisfactorily) anonymized, and analyzed and sent back to my smartphone to make route decisions when commuting. But its a slippery slope that consumers slide down over and over. I recall days gone by where SUN Microsystems engineers engaged in heated debate about caller ID and whether that was too much an invasion of privacy. Then, they argued that online sales would never take off because of the weakness of Internet security. Yahoo's patent application seems to me to be a natural outcome, once our smartphones are outfitted with so much sensing capability. Be outraged, but don't be surprised.
