Currently, about 600,000 people sign up for a Twitter account every day, but it took Twitter almost a year-and-a-half to attract its first 600,000 members, the company said on Friday in its .
In its first day, users sent 224 "tweets," which is the number the current user base sends every tenth of a second.
Meanwhile, the company's engineering team disclosed that users send 350 billion "tweets" every day.
Last week, Twitter said that it had recently topped 1 million registered applications for its platform built by 750,000 external developers.
The usage metrics released by Twitter contrast with the ones that Google CEO Larry Page provided about the company's new Google+ social networking site on Thursday.
