At the Web 2.0 Summit in San Fransisco last night, CEO Dick Costolo unveiled numerous mind-boggling statistics about his real-time, microblogging social slash information network platform thingy (read: Twitter).
Twitter now delivers 250 million tweets per day—up from 100 million at the start of 2011—which equates to nearly 175,000 tweets per minute. These tweets are coming from more than 100 million active users, including over 50 million daily users (now pause to consider the fact that Justin Bieber has 13.5 million followers). Now seeing almost two billion tweets per week, Dick notes that it took the startup over three years to reach its first billion tweets.
Mobile is Twitter's driving force, growing by 40% per quarter. And with the launch of iOS 5 (it boasts deep integration with Twitter), growth has accelerated even further.
On stage, Dick was asked, as usual, about Twitter going public—to which he responded, that with $800 million raised in funding, they're financially set for a while. So, no need, no timeline.
