Yik Yak App
It’s all about messaging nowadays and Yik Yak is banking on the preference to post anonymously via geo-located community forums. College students, high schoolers, and even some elementary school kids love this app as it allows them to forego a username as well as password. No handles at all, simply the ability to reach anyone within 1.5 miles of where you are. A “local” phenomenon to be sure.
