While making his rounds before Facebook’s IPO today, CEO Mark Zuckerberg pointed out that optimization of the platform’s mobile app was the main priority of 2012. Perhaps Zuckerberg plans to work some of this out himself, as he’s also declared that he will now write code every day in 2012, as if running a multinational corporation wasn’t enough.

This wouldn’t be the first time Zuckerberg had set out to complete a year-goal – in 2009, he vowed to wear a tie to work every day, in 2010 he learned Mandarin and in 2011 he only ate meat he killed himself. So, now it’s coding. It was recently reported that Zuckerberg is worth about $4.5 billion dollars. With that sort of money, he could buy the island nation of Kiribati, declare himself king, and do whatever he wants, forever. Or, at least not write code or wear ties.

It’s clear the young CEO that has been making investors nervous by merely wearing a hoodie lately isn’t some maverick who lacks focus. Interestingly, Feross Aboukhadijeh, a former intern at Facebook told New York Magazine that Zuckerberg had a bit of a hard time coding for Facebook’s Group feature, as the team was getting the product ready fro launch in 2010. Still, it’s been a very long while since the CEO was sitting in a dorm room at Harvard, developing the social network.

Today Facebook goes for $16 billion at a $104 billion valuation. Go here for extensive coverage.
