Opera: Facebook largest mobile social network, Twitter fastest-growing

[Norway] Browser maker Opera this morning released their latest State of the Mobile Web report, this time zooming in on the rising trend of social networking on the go. For the first time, Facebook comes out as the most-visited social network on the mobile Web, but Twitter‘s growth has surged even faster in 2009.

According to the report, unique users of Facebook grew more than 600% during 2009, helping the site surpass VKontakte, the Russian social network that was formerly the most popular among Opera Mini users (the browser is quite popular in Russia and Eastern Europe).

Twitter saw its usage increase more than any other social network, surging more than 2800% in just one year.

Opera reports that social networking on the go is a universal trend, and that all social networks have seen an increase in usage last year, with the notable exception of Friendster.

In December 2009, more than 46.3 million people used Opera Mini, an 11% increase from November 2009 and more than 159% compared year over year. Those 46.3 million people viewed more than 20.7 billion pages in December 2009.

Since November, page views have gone up 10.1%. Since December 2008, page views have increased 223%.
