> This should be a fun intellectual challenge to code this for myself. I'm looking forward to sharing what I learn over the course of the year.
I would be seriously impressed if he still had the technical chops to build and code this kind of ambitious project on his own.
It's also interesting that he's opening his life up like this and promising to share his (somewhat) individual work with the world, which most CEOs would never do. It has the potential to open him up to critical scrutiny and/or change his public persona. You would never see Musk releasing any updates on personal (less-ambitious) projects because it would detract from his hard-earned and paid-for superhero/wunderkind persona.
Seems like Zuck wants to be perceived more as a fun, quirky, techie rather than the corporate CEO of Facebook. On the plus side, he'll probably get to spend a lot more time with his daughter if he's hacking around the house all day :)
