Facebook in Privacy Breach

Facebook says it is taking steps to "dramatically limit" the exposure of users' personal information, after a WSJ investigation showed that personal IDs were being transmitted to third parties via Facebook apps. But how hard is it to fix such a breach - and how concerned should users be about the sharing of these IDs? Julia Angwin joins Digits to discuss.
