"Twitter has been under new pressure since its IPO two years ago, as investors and analysts have scrutinized its user numbers and expressed disappointment that they haven't grown faster. The company reported 316 million monthly active users in the quarter ended June 30, up from 276 monthly active users in the quarter ended June 30, 2014."
