Facebook has updated an API used by third-party applications to that allowed for cross-posting. The change breaks this functionality and one of the biggest impacts was felt by Twitter. Twitter users will no longer be able to create a Tweet and share it easily to their Facebook page.
Twitter has cut Emojitracker's access to its Streaming API, causing its creator, Matthew Rothenberg, to announce that he will shut the service down in April. Emojitracker provides a real-time visualization of emoji symbol usage on Twitter and has tracked some 14 billion emoji tweets.
