Yik Yak is an app that allows users to communicate anonymously with anyone within a 10-mile radius. In the first part of this week's show, we revisit a story we did in January,  about how the app brought out a particularly vicious strain of racism at Colgate University. And in the second half of the show - The past month has seen a flood of similar stories at colleges like University of Missouri, Yale, and Georgetown. So we go beyond Colgate and talk to Jamil Smith of the Intersection podcast to try to understand Colgate in the context of these recent events.
