AFP, SAN FRANCISCOTwitter Inc shares on Tuesday gained on word that cofounder Biz Stone was returning to the social network after six years away. “Excited to have Biz’s energy and heart back at Twitter,” Twitter cofounder and CEO Jack Dorsey said from his @Jack account with the hashtag #BizIsBack. Stone left Twitter in mid-2011 during executive shake-ups and joined cofounder Evan Williams in forming a start-up called Medium. Twitter last month reported first-quarter results that were better than most forecasts, but continues to struggle for momentum in revenue and use. Twitter has been seeking to broaden its appeal beyond its core user base of celebrities, politicians and journalists, ramping up efforts in video and live sports.
