Sure, Ron. The -- well, the nice thing about the first quarter results are frankly that they are an accumulation of the hard work we've been doing over the last 3 or 4 years to improve the user experience, both the product experience, the trust, the quality of products on the site, the quality of sellers. And so the data I look at is buyer retention. And buyer retention is up in the U.S. and across the globe. The second thing, as you know over the last several years, people have been saying, "When are we going to start marketing to bring back inactive users or bring new users to the site?" And under Devin's leadership over the last really 6 months, we have really ramped that up. As you know, we did a brand campaign in the fourth quarter, and we're starting to start marketing. And Devin and I were just sitting down; he was showing me some data yesterday where our active buyer growth is up 9.5% in the core Marketplace business. So we're beginning to reach out to people that haven't used eBay in a while or never used eBay, and they're responding. And they like what they see. So I think that's adding to the growth and that's adding to our optimism. And then as you said, another focus Devin's brought is the focus on the BRIC markets. And we were going through some data, just some of the fact that -- the user growth, the buyer growth in some of the BRIC markets, in India, in Brazil and Russia, in Eastern Europe and in China. And they're very significant user growth rates. Now they're under relatively small bases. And right now, they're importing product. But as large numbers of new users come online in the BRIC markets and in the -- and in emerging markets, they won't have a local e-commerce market at first, and they're going to be looking to kind of global e-commerce sites that specialize in cross-border trade. That, of course, is what we do. eBay does it, PayPal enables it. And so again, I think that we'll see increased focus and we'll increase focus on bringing buyers to the site, both in the U.S. and around the globe, and then try to deliver a great experience so that we retain those buyers. And you add that together and that's why we're optimistic. I'll also say we have a couple of -- a nice series of product enhancements during the year. You're going to see some really, really good stuff around the checkout experience on eBay. We're finally going to -- given the fact that we own eBay and PayPal, we're going to improve the checkout experience on eBay. You're going to see some search improvements. You're going to see some fun areas and discovery, and so things -- more to come on a steady stream of product enhancements on eBay. So all in all, we're feeling good about that business.
