How 2 Georgia fraternity brothers created Yik Yak, a controversial app that became a ~$400 million business in 365 days
Last March, an app called Yik Yak took over Elizabeth Long's high school, Woodward Academy, in Atlanta. Students learned about it during first period. By lunchtime, the school made an announcement: Anyone caught with Yik Yak on their phones would receive automatic detention. The reason? Too many students were using the app to bully their peers anonymously.
