I am a London-based product manager.
What’s the value exchange between me and Google? Not a question I gave a second thought to... until I noticed a few disappearing yellow stars.
I spend around 10 minutes a day on Duolingo and I’m not convinced it’s worth it. And the fact these doubts only started occurring to me after I completed a 100 day streak on this maddeningly well-designed and moreish app is… annoying.
