This month Facebook announced that the social network site has got more than 350 million active users. Each user spends an average of 55 minutes each day on Facebook.

In 5 years Facebook has grown from 1 million users to an impressive 350 million users. 300,000 Facebook users helped to translate the platform in 70 different languages.

Each month users upload over 2.5 million photos to their Facebook profile and share more than 3.5 million pieces of content (weblinks, news stories, blog postings, notes, etc.) each week.

Currently there are over 350,000 active Facebook applications, built by 3rd party developers. 250 of these applications have more than 1 million monthly active users.

Approximately 20% of the active users access Facebook through their mobile devices. These users are almost 50% more active on Facebook than non-mobile users.

Will Facebook grow to 500 million users in 2010? If Facebook does, they will be bigger than Microsoft’s Live network that currently has got more than 500 million users.
