Learn Exponentially
My idea is that there is a market for community-curated spaced repetition decks. Many people want to learn the same things such as a foreign language or a programming language.The difficult part is creating a deck and crafting the answers and questions. Because usually this is a time-consuming process. So if it was a community-effort then it would be a win-win.This is probably not an original idea and if anyone knows already where to find such decks, that would be cool.
