Twitter disappoints investors with recent growth numbers

Twitter said Monday its monthly active user base expanded to 284 million users during the July-to-September quarter, an increase of 13 million over the previous three-month period. While that might sound like decent enough growth, some investors had been expecting a more impressive figure. The numbers, revealed on Monday as part of the company’s financial report for Q3, also suggest the rate of growth is slowing after Twitter added 16 million new users in the April-to-June period and 14 million in the quarter before that.
