Yeah. Hey, Ron. I'll take the first. Yeah, when you think about the here and now, you know, when we call this out in our letter really around product optimizations. And, Ron, I'll kinda just let's just start, like, three parts. Step one, people come to Airbnb, Inc. It's really we have a huge amount of traffic. We have nearly 5 billion visitor unique 5 billion visitors a year. It's really important that, like, when people come to Airbnb, Inc., they are able to find the right Airbnb, Inc. for them. We've done a lot around, you know, like, we've introduced a personalized welcome tour. Again, people use Airbnb, Inc. only a couple times a year, so it's really important to orient them. So we've got this welcome tour that's personalized to every person. Based on your past searches, we suggest destinations that you we think you're gonna be interested in. Based on past filters, we offer up those filters as essentially, like, quick filters to apply. We've also found that, you know, this is probably obvious, but, our mobile app converts significantly higher than our mobile website. So we've been pushing to get more people to download our mobile app, and now in Q4, mobile bookings represented 60% of our overall bookings up from, I think, 55% the year before. You know, our checkout page, it this sounds like a simple thing, but the checkout page like, the page to to pay, not the checkout Airbnb, Inc., the page to pay, was really, really long, and we found that if you make it shorter, simpler, that leads to a massive increase in conversion. I'm just giving you a couple examples. There's really a long list of dozens and dozens of things again, you know, a hundred basis point increase on a GBV of $80 billion, you know, you're gonna be soon approaching like, $100 million optimizations just one at a time for some of these really, really big efforts. So once you find an Airbnb, Inc., it's important that that Airbnb, Inc. is affordable. And affordability is in our DNA. So we've made a lot of improvements around affordability that have also increased optimization. Like showing the total price display. When guests toggle on total price display, that includes all fees including cleaning fees, we see that people are booking higher value Airbnb, Inc.s. We've also created a lot of tools for hosts. Whether it's monthly and weekly monthly discounts, price tips, search tips, all these things are essentially efforts to make everything more affordable, and it's working. Because during 2024, hotel prices were up year to year while comparable Airbnb, Inc. listings were down year over year in price. So we're making progress. And the last thing is if you find the Airbnb, Inc. is a good price, it's still really important that it's of high quality. For every person who books in Airbnb, Inc., about 90 people book a hotel. And so if we do, you know, around a 500 million IT year and we got the extra hotel grass to use Airbnb, Inc., go from 500 million nights to a billion room nights. So that's a really, really big opportunity. And we think the number one way to do that is to improve the reliability and quality of our service especially your host. So the way to do that is elevate the best and cut the bottom. We introduced guest favorites in October 2023, it's now gotten 250 million nights booked. If you book a guest favorite, customer service rates are down. Trip issues are down, guest net promoter is up, cancellations are down, so it's really great. We also since April 2023, we introduced a new host quality system and removed 400,000 listings that don't meet our or don't meet our guest expectation. Ron, those are essentially the three levers. We have usability, making it easier for people to find the listing by increasing conversion. Affordability, getting prices to be better and more competitive, and then reliability and quality of the service. So again, we've made know, hundreds of updates over the past few years on these, but these are just a couple callouts.
