While Facebook has previously avoided supporting GIFs out of fear that a thousand dancing cats might pollute the look of its news feed, Twitter has solved the issue by including a play button that users must click if they want to see a GIF in action.
For all intents and purposes, Twitter is the digital age's leading method for breaking-news delivery and consumption, and, believe it or not, GIFs have become a huge part of that delivery system. While the looping image format is rooted in humor, if a singular moment that requires re-watching ever occurs, it's only seconds before the Twittersphere collectively calls out for a GIF. Jennifer Lawrence falling at The Oscars and Felix Baumgartner’s space dive come to mind. If Twitter wants to continue to be the populist service that it's become, adopting GIFs was an essential move.
Just take one look at your new timeline and you'll see what we mean. The excitement is palpable. So go on, start tweeting GIFs with reckless abandon. Just make they're 140 dance moves or less. (The Verge)
