HubSpot's new Dan Zarrella conducted an interesting analysis of "more than 70,000 Facebook public posts" and found that "32.69% of those posts were created from mobile devices." Apps collectively account for roughly 13% of mobile updates, while facebook's mobile website (m.facebook.com) constitutes roughly 19% of mobile posts.
Facebook has more than 250 million active daily mobile users around the world. And it is the most "engaging" mobile property in terms of time spent (see below). At some point the company we can expect that the site will turn on mobile advertising. There's a version of that today in the form of "check-in deals."
