The structural change comes from this point of openness. We talk about this concept of openness and transparency as the high level ideal that we’re moving towards at Facebook. The way that we get there is by empowering people to share and connect. The combination of those two things leads the world to become more open. And so as time has gone on, we’ve actually shifted a bit more of a focus not just on directly making it so people can use Facebook and share and be open on Facebook, but instead on making it so that the systems themselves have open properties.
