Should authors use Snapchat to target a younger audience?

Teleread asks if authors should be using the Snapchat social media platform to promote themselves. Why?

"In this article on Brand Driven Digital, Nick Westergaard gives Snapchat a look and explains why it matters. Here’s why young adult authors and publishers should pay attention: “nearly half of Americans 12–24 use Snapchat.”

Oh? The exact audience that young adult writers crave."

This begs the question: Should libraries be using Snapchat?
