But, you know, one of the most powerful things we found is many years ago. So we send you a notification. And then if you don't use Duolingo, we send it to you the next day and the next day. After five days of inactivity, we stop sending you notifications because we think, you know, we're not going to spam you forever.

One of the things that we found is, you know, we thought, well, if we're going to stop sending notifications after five days, we may as well tell you that we're stopping. You know, we're being nice to you. We're not going to spam you forever. We may as well tell you. We didn't think this was going to bring people back.

But what we did is we started sending the last notification that we send says something like, these reminders don't seem to be working. We're going to stop sending them for now. We thought we were just being nice. I didn't realize. Yeah, you're being honest. Yeah, but I didn't realize this was an extremely passive-aggressive way to get you to come back.

It works really well. It works really well. And that notification, not only did that notification work really well, it also kind of became the basis of our voice.

And he's willing to go through great lengths, including kidnapping your family or whatever it is for you to do your lesson. But it all came from that notification. And then there's all these memes that came about. And our voice really was found.

No. It's universal. We have heard so much from people who tell us that there are differences. And we also employ country marketing managers in every country, not every country, in every large country.
