"Stephen Baker calls such whizzes [creators of data analysis programs] the Numerati. Using 'data mining,' they seek out veins of useful ore in the mountains of facts that computers accumulate every day."
"The Numerati are even mining the output of bloggers, those stream-of-consciousness online diarists and self-promoters. 'What makes the blog world especially valuable to marketers,' Mr. Baker writes, is 'its unfiltered immediacy.' What do consumers think of your new product? What desires are still not satisfied by products of this kind? You can commission a poll or wait for the sales figures to come in . . . or you can read the blogs. Better yet, you can hire Numerati to write programs that will read them for you, since there are now more than 20 million bloggers in the U.S. alone."
