Yik Yak on Tuesday began allowing users to choose a screen name, a shift for the social media app known for anonymity that may help reduce trolling and cyberbullying. Tyler Droll and Brooks Buffington, who founded the Atlanta-based company in November 2013, told The Huffington Post in an interview that the new feature is designed to increase engagement and attract new users from outside their core base of college students. It also aims to combat trolling, they said.
