Yesterday Twitter launched a new video service called Vine. Vine is a mobile service that lets you create and share short looping videos (6 seconds or less). Vine is currently available free for the iPhone and iPod Touch from the App Store. It seems like Facebook is refusing to authorize requests for Vine users to find their Facebook friends. The error says “Vine is not authorized to make this Facebook request.” Facebook and Twitter’s rivalry is quite intense. This past July, Twitter blocked Instagram from using their friend-finding API. They followed that up by blocking Tumblr.
