According to Twitter CTO Dick Costolo, about 65 million tweets are sent on Twitter each day. This equates to roughly 1.96 billion tweets per month, a stat that’s corroborated by Pingdom’s estimate of 2 billion tweets per month.Just over a week ago, we reported that Twitter hit the 15 billion tweet mark. The service announced its ten billionth tweet just a few months before that, and hit the one billion tweet milestone back in the fall of 2008. Twitter’s growth curve is clearly accelerating.
Costolo also stated that the service sees around 135,000 new registrations each day; we’re not sure how many of those new users are unique people versus new accounts for business or other purposes. Another unknown is exactly how many of these registrations end up being regular users of the service and how many accounts drop off after a month or two.
