Ryan Calo, a residential fellow at Stanford Law's Center for Internet and Society, is quoted in the San Francisco Chronicle on the difficulties of erasing one’s digital footprint:
It's been almost two decades since mainstream users began trekking into the library-slash-playground known as the World Wide Web. Now, several years into that excursion, many are taking a long hard look at the trail they've left behind.

"There are lots of ways for you to inadvertently send your information to the Internet," said Ryan Calo, a residential fellow at Stanford Law's Center for Internet and Society. "It surprises me, even as a person who has worked in this field for a number of years, how easy it is for information to flow from one point to another."
