A class blog post on Metadata World discussed a New York Times article “Stop Asking Me for My Email Address.” This is the dark side of metadata creation: companies using our personal metadata for profit. And it is a big business of so-called “Big Data” as retailers like Target keep stores of data on our buying habits and interests in order to better advertise and sell more stuff to us. Pioneer techie, Jaron Lanier has written a book, Who Owns the Future, that discusses this, and he proposes companies pay us for our data. Anyone read this? Any opinions?
