If I may just add to that, on the specific thing about reaching out to the broader ecosystem and working with partners, certainly we do that in Canada with MediaSmarts, as I mentioned, which is Canada's digital literacy organization. They work closely with schools in classrooms across the country. I think that is an important ultimate backstop.
That's not to say that we don't have responsibility on our part, and I think Rob was very clear. Not only have we historically done this, we're doing more. I think the recent controls we've announced make it even easier. Before this, I think you had to go to potentially up to 20 different screens to control your experience on Facebook. We're now centralizing all of that in one map, if you will, where you can play with all the dials and have complete control over your experience and your privacy on Facebook.
We completely agree that it's very important, and we are moving to roll that out, not just in Canada but around the world.
