After closing a massive new round of funding, Twitter CEO Dick Costolo has casually mentioned that Twitter now has 100 million active users . Back in April, Twitter officially passed 200 million registered users, so this new milestone also serves to remind us how many users simply don’t use their accounts.
Twitter says the proportion of inactive users is around 50%. Still, this news proves that the service has managed to continue adding active users. Costolo also said in his presentation that Twitter is seeing an average of 230 million tweets per day.
Much of the continued growth is coming from mobile devices. Costolo reported that 55% of Twitter users are accessing Twitter on their phones. Of course, none of this says anything about the quality of the content from the new accounts. What’s your read on that?
