Julia Angwin , The New York Times; Breaking Up Google Isn’t Nearly Enough
"Competitors need access to something else that Google monopolizes: data about our searches. Why? Think of Google as the library of our era; it’s the first stop we go to when seeking information. Anyone who wants to build a rival library needs to know what readers are looking for in order to stock the right books. They also need to know which books are most popular, and which ones people return quickly because they’re no good."
