Facebook stock is finaly trading today, which, of course, you know by now.  And while everyone else is glued to the stock ticker, or hanging with Zuckerberg and tweeting about valet parking, we thought we’d pull out our crystal ball and look to the future of Facebook and mobile. According to Businessweek:

More than half of its 845 million monthly active users accessed the social network through mobile apps or its mobile website, both of which sport no ads.  Which in and of itself isn’t dire, because most of those people also log in on their computers.  

But:

“The big concern is the mobile-only audience is growing faster than the multichannel or desktop-only audience,” says Elkin [ter principal analyst Noah Elkin] . “The long-term concern is that the mobile-only audience will come to dominate the social network.”

So it’s clear it’s a future that Facebook needs to figure out mobile fast, in order to keep shareholders smiling.  And to keep paying the valet guy.
