It's a good idea to make a service that claims to help you be cheap. Duolingo doesn't have any intrinsic claim to take up a large space in people's lives, so it might be a good idea (if their goal is to help people learn languages) to remain as tiny as possible while being effective over some threshold. Then it would easily fit in people's schedules. Their motivation seems to be engagement with the app, not language learning, and I make this judgement by noticing that engagement tools have changed over time, but language learning has not (visibly).

Sure, but a little bit of daily engagement is a reasonable approach to that. > Their motivation seems to be engagement with the app, not language learning True, but daily streaks are a plus for language learning, so it makes no sense to attack the practice of tracking daily streaks. Duolingo is not an effective use of your time if you want to learn a language. But if we assume that the options are Duolingo or nothing, you're better off using Duolingo every day.
