Twitter signups jump since iOS5 launch

With Apple Inc.'s iOS 5 now integrated with Twitter, the micro-blogging site has seen a jump in Twitter signups via iOS 5 devices. Twitter CEO Dick Costolo said Twitter signups via iOS 5 devices tripled since iOS 5's launch last week, tech site Mashable reported. Costolo revealed these stats during an interview at the Web 2.0 Summit in San Francisco. Although Costolo did not immediately cite specific figures, Mashable said the direct integration of Twitter into iOS 5 has resulted in a boost for Twitter. Costolo also disclosed Twitter now has more than 100 million active users. Earlier, Twitter disclosed it had surpassed 200 million tweets per day in June, but has since jumped to nearly 250 million daily tweets. Twitter had around 100 million tweets per day in January 2011. Of those 100 million global active users, half of them log in daily, Costolo said. “We had 30 percent of our monthly active users logging in every day at the beginning of the year. Now it’s over 50 percent," he said. The company’s growth amounts to about 40 percent quarter on quarter, Mashable said. — TJD, GMA News
