Thanks, Ben. I'll share some further details on the trends we saw in Q2 and provide a preliminary outlook for Q3. As noted in our shareholder letter, fewer monthly active users came to Pinterest in Q2 than we expected. Ben's remarks on the letter detail why we think this happened. But in summary, we believe that nearly all of what we're seeing now is the unwinding of some of the engagement benefits that we got during an unprecedented period of time when people were stuck at home and had more time to spend on some of our core use cases. We also continue to monitor other factors, including competition and the impact of Google's recent search algorithm changes while continuing to improve our product and ramp up our marketing efforts to increase engagement over time. We're encouraged that our most engaged monthly active users, those that use our mobile applications, grew year-over-year, both in the U.S. and globally. These users contributed a significant majority of both total impressions and total revenue in Q2. Additionally, the investments we've been making to more efficiently realize value from the unique existing engagement we have is working well. Specifically, the engagement we have on shopping services appears to be more resilient than overall engagement. We plan to continue investing in helping Pinners shop for products they love at a price point they want and in helping merchants get discovered and connected to people who will love their products and services. While we're still early in the journey to fully monetize our shopping engagement, we believe that we have the right sales coverage model, and we're delivering conversions to advertisers who are seeking sales on the platform. Looking beyond the COVID-19-driven volatility, our view on the long-term opportunity to grow our user base, both in the U.S. and globally, is unchanged from what it was before the pandemic. Turning to our financial performance. Year-over-year revenue growth accelerated to 125%, with adjusted EBITDA margins of 29%. This remarkable growth was propelled by 2 main drivers. First, we saw momentum from large advertisers, especially retailers, who returned to the platform in force as consumers resumed social activity when pandemic restrictions leaves. Other going out subverticals like beauty and travel also returned to strength in Q2. Second, our international business again performed really well, growing 227% year-over-year in Q2 and contributing 22% of total revenue. Both of these trends show the growth and diversification of our active advertiser base, which grew both sequentially and year-over-year. Turning to our preliminary outlook for Q3. The engagement headwinds we observed in Q2 have continued in July. As of Tuesday, U.S. monthly active users have declined approximately 7% and global monthly active users have grown approximately 5% year-over-year. The evolution of COVID-19 and pandemic restrictions remain unknown, and we're not providing guidance on Q3 2021 monthly active users, given our lack of visibility into certain key drivers of engagement, which could continue to play out for a few quarters. On the revenue side, we expect total revenue to grow in the low 40s on a percentage basis year-over-year. Please note that our Q3 revenue guide takes into account a few things: first, Ben talked about the important transition we're making from being a place where people view static images safe from the web to the place where people go to discover the best native immersive lifestyle content. That's a big behavior change for us. To build a new ecosystem for creators, we have to invest, and that means giving distribution to Idea Pins at the expense of some high-value advertising inventory, which impacts revenue. We believe that in the long term, this strategy will be engagement accretive and that we'll have a significant opportunity to monetize that engagement. [Technical Difficulty] through the course of the year and in Q3. There was a big rebound in ad spend during the quarter as large CPG and retail advertisers reengaged after the initial shock of COVID, and we believe we benefited from being a positive platform during the social media boycott amidst the 2020 election cycle. Finally, we're carefully monitoring the impact of increasing prices on the platform. These increases are consistent with our strategy to grow our advertiser base, increase auction density and deliver ads more efficiently over time, but that may increase the churn for some price-sensitive advertisers whose cost per action has increased. Before opening it up for questions, I also want to touch on expenses. We continue to invest in the growth of the business in accordance with our key strategic priorities of inspiring content, the Pinner experience, advertiser success and shopping. Non-GAAP operating expenses grew 51% year-over-year, driven in part by our brand marketing campaign. We increased our head count 21% year-over-year, our third quarter of sequential acceleration. We expect sequential non-GAAP operating expenses to grow modestly in Q3 as we continue to ramp investments in our long-term strategic initiatives and growth drivers and resume our brand marketing campaign again in early Q4. Thank you to our teams at Pinterest, our advertising partners, our creators and all of the people that come to Pinterest to find inspiration. And with that, we can open it up for questions.
