Great. Thanks, Chloe. Why don't I start on the user engagement? I think you're also asking about ad engagement, so kind of performance. And then I'll let Mike take the second question on personnel growth and so on and how that flows through OpEx. So on user engagement, just to remind, third quarter of accelerating WAU growth, we're really pleased with that. We think that continues to flag both improvements on the product overall, some notifications, Connections, evolution of the news feed and then better ads but also retention as well. And we've not really talked about that on the call yet, but we continue to see really strong retention rates as well. Back at Investor Day last year, we gave you retention rates of after 3 months, we see 75% retention of MAUs; after 6 months, 65% retention; and after 2 years, still more than half of new neighbors are actively engaged. And we know that, that is kind of world-class. Those trends have stayed consistent. And in fact, over the past 3 quarters, we're seeing increasing retention, especially for people who've been on the platform for more than a year. So that's always a great sign that users who have come, who have found value keep coming back for more. And then I think the other point I would make there is actually our strongest retention trends are amongst our daily active users. So this is also why it's important to keep moving people down that funnel from being a verified neighbor to a monthly active, to a weekly active, to a daily active. Because when we get you to daily, your ability to keep coming back, your retentiveness is much higher. On the ad side, what we are seeing is, as we shift more and more of our own proprietary data into the platform, frankly, as we make the ability to self-serve, so to be much more innovative with your creates and so on, make those ads more engaging, we're starting to see better and better performance. I talked about The Farmer's Dog during my prepared remarks, but that's a great example of a home delivery pet food company that came to Nextdoor test, then they went full-on, and they've actually been greatly increasing their spend in Q2 over Q1. And really, that's a result of much higher click-through rates and really to the metrics that they measure. Nextdoor is a platform that can both act top-of-funnel for advertisers, so in brand and awareness driving, but also bottom-of-funnel direct response. It's about a 50-50 split, maybe erring a little bit more into direct response right now. And I think it's important that we can do both. I'll pause there and maybe, Mike, do you want to take the question around the head count personnel growth and so on?
