"A new analysis of online consumer data shows that large Web companies are learning more about people than ever from what they search for and do on the Internet, gathering clues about the tastes and preferences of a typical user several hundred times a month." (Here.)
Not news per se, but it's slowly becoming a topic one discusses in polite society.
"These companies use that information to predict what content and advertisements people most likely want to see. They can charge steep prices for carefully tailored ads because of their high response rates."
And the gloriously elegant market solution that will soon perhaps present itself is that the consumer may herself shell out for the opportunity of "ad-free," or ad-minimal, or very likely "ad-invisible," cyberspace--adhering to the good taste (aesthetics, manners, anti-vulgarity) of very few ads, as though one were tucked away in the high green hills, far from the billboard-littered boulevards where strip malls and blocky superstores pollute our visual quotidian.
