Yik Yak to Shut Down

Yik Yak, the once-popular anonymous messaging app, will shut down in the coming weeks, its developers announced Friday. The app was once at the center of several campus controversies, but a series of decisions to limit completely anonymous posting drove many users away. The company behind Yik Yak, once valued at between $300-400 million, in February announced a new group messaging app. Last month, many of its software engineers were hired by the payment solutions provider Square.
