Vine Becomes Number One App In U.S. App Store | Fast Company | Business Innovation: Vine, Twitter's six-second video app is at the top of the App Store download chart in the U.S. The news was announced on Twitter by Vine's creative director, Rus Yusupov, with a screenshot (but no backslap-fist pump video offering, sadly.)
