At Facebook we feel a lot of affinity not just for this community but for any community that is trying to do what Davos is trying to do, which is to share information. And Davos is doing it in a particular way - I think the Facebook approach is obviously more broad-based, we're trying to include everyone in the world. But the goal is the same: bring people together, to share information and make the world more connected, and have people have a deeper understanding of themselves, others, the communities of which they want to be a part and can be a part.
