Due to Twitter's popularity it has jumped in the overall internet rankings, last year it was the 969th most visited site on the web. It's now the 38th most visited website.
The news gets even better for Twitter as Hitwise are only measuring traffic to the main Twitter website, if people are accessing their Twitter accounts via mobile phones and third party applications like Twitterific or Tweetdeck were included, the numbers could be even higher.
Micro-blogging site Twitter has also had a major impact on so-called 'citizen journalism', when members of the public use the site to break major news stories or updates such as the terror attacks in Mumbai or the recent protests in Iran.
But the social networking website still has some work to do to catch the likes of MySpace, Bebo and Facebook.
