Trace covered Facebook's Q1 earnings earlier tonight, and touched on the social network's insane numbers - but they really do need their own story they're so gigantic. Facebook now have over 1.11 billion monthly active users, and a chunk of those are on mobile.
During March 2013, daily active users passed 665 million on average, and there was a huge 751 million monthly active users, too. The 665 million daily active users (DAUs) is an increase of 26% year-over-year, with the 1.11 billion monthly active users (MAUs) being an increase of 23% year-over-year. Mobile MAUs sitting at 751 million is an increase of a mammoth 54% year-over-year.
As you can see, the center of all of this is mobile. Facebook know this, and are pushing out better mobile apps, such as Home. Sure, I use Facebook on my desktop, but I live on it on my mobile - if I'm away from my desktop or notebook, I'm on my Facebook app constantly.
