The days of the internet as a vast, untamed frontier are over, and Eli Pariser wants to make sure you know it. Pariser is the 30-year-old president of
moveon.org, and with his new book
The Filter Bubble: What the Internet Is Hiding from You, Pariser brings a civic-minded skepticism to bear on the increasing "personalization" of the Internet. The primary value of

Pariser's biggest accomplishment here is in clearly identifying and unpacking an often unacknowledged aspect of our digital life. ALISON HALLETT
