Facebook Gains 20% on Unexpected Earnings Increase

After a rocky year and a tough market for IPOs, Facebook

shares rose more than 20 percent this morning.

Investors were particularly impressed with the company's 32 percent increase in revenue and its 61 percent year-over-year increase in mobile MAUs (monthly active users), as well as its ability to profit from mobile devices.

Three weeks ago, they had more than 48 million users each. Despite these declines, Zynga is not likely to shut its doors anytime soon. But if that day comes, Facebook will be forced to fill a significant void. Now that the company has shown that it can profit from

, Facebook might want to re-evaluate its social gaming strategy.
