Polly is the latest app to tap Snapchat for growth

Snapchat doesn't have a "platform" for helping outside developers build products using the ephemeral messaging app, but that isn't stopping them. One of the latest examples of apps building their following through Snapchat is Polly, a young app for creating and answering fun polls. Anonymous feedback app Sarahah is another example.

Our thought bubble: It's obvious that Polly is capitalizing on current popular trends, namely Snapchat and polling apps. Less clear is whether it has staying power. Many social apps burst onto the scene and fade away just as quickly. Another key question is where Snapchat will go. It could take formal steps to work with outside developers who want to plug into its social network as social media giants like Facebook and Twitter have. So far, however, the company has declined to even build tools for brands and celebrities, so we're not holding our breath.
