The reason Snapchat will fail is that low-obligation communication has no sustainability. It’s not much better than trying to spam DMs to all your social media followers, except you look more ridiculous as an adult wearing a puppy face. Just saying. I didn’t see any value in the platform for me and left it as soon as I joined it. Tumblr has meat in conversations if you want to see what some of the younger members of the community are in to.
