Yik Yak you can't take that performance back

What it is: Yik Yak is a college/high school platform that delivers anonymous commentary, jokes and news to a home community (the stream is limited to a tight radius like a college campus). It's on more than 1300 campuses and estimated value is in the hundreds of millions.

Why it matters: It would primarily be useful as a listening or intelligence tool in the B2B community but if you are considering particular recruitment campaigns or speeches on college campuses, let Ted Cruz's Liberty University speech be fair warning, the media is already listening to Yik Yak and sharing the results with their audiences. The posters might remain anonymous but your performance certainly won't.
