Twitter Co-Founder Biz Stone Is Returning

Stone, who left Twitter in 2011 and recently sold his startup Jelly to Pinterest, announced in a blog post Tuesday that he’s headed back full-time to the company he helped found. It’s not exactly clear what Stone’s title will be, but a source familiar with the move says he’ll report to Twitter CMO Leslie Berland and help with internal communications and morale at the company.
