“We had an employee who lost her, I think a four-month perfect streak, and it was a big deal for her because she did her lesson, and she was crossing international dateline, there was a bunch of stuff going on that was like, it was just kind of weird in our backend.”

Transcript context

…That's so funny. Okay, anything else? And if there's more than one more, definitely share, but any other really interesting lessons or wrong turns or insights? I talked about streak freezes, and we've done a lot with streak freeze, but I think if you're going to make flexibility a thing, it's probably also useful thinking about how do you celebrate perfection. And so, we have a feature that we have, it is the simplest thing in the world, it's called Perfect Streak. And it's just, if you don't use the streak freeze for a few days, we make your streak look gold, and we make your little progress bar on the calendar just look a little bit nicer. There's no reward for doing it, you don't get anything other than this nice little indication, and it is awesome. It is a simple feature, it is ultra not complex, and it is really powerful, not only for getting users to, as a bit of a reward, they'd be hey, get to seven days without using a streak freeze and your streak becomes perfect, but it's also a really nice indication of users who aren't using streak freezes. Here is the thing that if you don't use a streak freeze, which, again candidly, I would love for you never to use a streak freeze, if you don't use a streak freeze, your streak will stay perfect. It's funny, we actually just, we're constantly responding to bug reports about the streak. It is... I swear to God, we have the best infrastructure around this feature because it is so important. We had an employee who lost her, I think a four-month perfect streak, and it was a big deal for her because she did her lesson, and she was crossing international dateline, there was a bunch of stuff going on that was like, it was just kind of weird in our backend. But people start to care about perfection as much as they do their streak, and for that person it was a big deal when they lost their perfect streak. And so, this is just an example of, look, if you're going to go after flexibility, which is good, finding a way to pull users back into perfection is a really important counterweight to have. What I'm imagining is you guys need a Amazon style chatbot that just gives you the streak back, it's just like, okay, here you go.…
