If you've never Vine'd, allow me to explain this for you. Vine is an app that is not accessible from any platform other than a phone application. It allows you to create 6 second videos that loop endlessly and then post them for people to see on vine OR you can link it to your twitter and/or facebook account. The purpose of the app is to allow the user to... well... um... I guess share 6 seconds of your life or creativity to people you already know.
