Twitter May Create Its Own Video Service Meanwhile, Jack Dorsey denies that he's prickly By Kevin Spak, Newser Staff Posted Oct 9, 2012 3:26 PM CDT 3 comments Comments A Twitter page is seen on an iPhone in Japan in this file photo. (AP Photo/Koji Sasahara, File) (Newser) – Twitter is looking into the idea of developing its own video hosting capabilities, so users won't have to turn to third-party services like yFrog, TwitVid, or Vodpod to share their videos with the world, sources tell All Things Digital. While Twitter still expects most users to upload their videos on services like YouTube or Vimeo, it thinks offering its homegrown option will help refine Twitter's user experience. Meanwhile, Twitter co-founder and Executive Chairman Jack Dorsey confirmed that he'd taken a step back from his operational role in the company, but denied a New York Times report that it was because "employees complained that he was difficult to work with." In a Tumblr post, Dorsey said he stepped back because he wanted to spend "the majority of my time with Square, where I'm CEO."
