Twitter continues gaining popularity visited by 73.5 mn people in January

It’s well known Twitter is gaining popularity increasingly alluring more and more users. This fact is proved by the figures presented by comScore that showed 73.5 million unique individuals registered in January. That is up 8% from December, 2009 (when it was 65.2 million visitors).

Twitter’s annual growth rate makes up a phenomenal 1,105%. A year ago, Twitter.com attracted only an estimated 6 million visitors.

Twitter has definitely been improving the functionality of its own site, with the deployment of new features such as local trends, a better suggested user list, Twitter Lists, and the Retweet button.

Meantime, ComScore only estimates activity on Twitter’s own site. Usage across other desktop, Web, and mobile apps may be twice as large as on Twitter itself.

CEO Ev Williams stated last month, that the service had its best day ever, and Royal Pingdom estimates that it passed 1 billion Tweets a month in December, and grew to about 1.2 billion Tweets in January, 2009.
