Facebook Blocks Twitter's New Social Video Service
It appears that Facebook is refusing to authorize user requests to find their friends on Twitter's new Vine social video service. Twitter user @MartinesJeff noticed the error, which reads, "Vine is not authorized to make this Facebook request." The specificity of the error message is intriguing; it almost looks as though the Vine app was already set up to explain a situation like this. Facebook and Twitter have long been battling each other over access to user data.
