I like to pride myself on thinking pretty long term, but not that long term.

We're very focused on making News Feed really good, making our photos experience really good, making messaging really good, and creating great location apps. That's the nature of a platform business of our scale. Most companies that are relevant to us will have some overlaps in some competitive way.

About half my time is spent on business operation type stuff.

If you just work on stuff that you like and you're passionate about, you don't have to have a master plan with how things will play out.
