Like many people, I started using Anki for language learning, and it has been wildly useful for that. I'm always told that I have a good vocabulary, which was precisely my problem last time I tried to learn a language. Since then, I've branched into many other topics. The latest one that I've started building out is all of the Paris métro lines and stops. The most useful thing ever? No, but I feel happy knowing that I have a better understanding of the system I'm using ever day.
