Twitter now has 100 million users worldwide

Micro-blogging website Twitter has announced it has reached a major landmark of 100 million users across the world.

Dick Costolo, the social networking website's chief executive, said at Twitter's headquarters in San Francisco that more than half of the 100 million users log in each day.

Around 40 per cent simply read the site, without tweeting themselves, he was quoted as saying by The Telegraph.

Twitter now generates more than five billion tweets every month, gets 400 million unique visitors every month and half of its active users log in through mobile devices.

Recently, the news that Beyonce is expecting her first child broke records on Twitter, with almost 9,000 tweets being sent every second about the singer.
