Social networking powerhouse Facebook (META -0.81%) has seen its stock shake off its post-IPO hangover in a big, big way. 

In fact, Facebook shares are up almost 100% over the last 12 months, nearly three times the market's return during that period.

And beyond just the performance of its stock, Facebook looks confident in many ways as it heads into its fourth-quarter 2013 earnings report on Wednesday, and rightfully so.

And Facebook's just really getting started.
