A friend and I decided to build an Anki replacement a few years ago, it's now located at https://www.memorangapp.com and has a loyal following of 10s of thousands of users. Anki is a great tool and has a wide variety of content on Ankiweb, however the ecosystem doesn't allow for any collaboration or the ability to keep content up to date (aside from manually editing decks, but where for example can you suggest a corr…
One of the things I realized after using Anki for a while is that school education isn't really even designed for retention - it seems built for cramming and forgetting. I'm just concluding that off of basic scale. After using Anki for a couple of coursera courses and being overwhelmed with cards for months until it calmed down, I realized there was no way I would have been able to keep up with retaining all learned…
I think the problem with Anki can be distilled down to root assumptions it makes about how people should ideally learn and how to model what is forgotten over time. In studying for a course there are basically three strategies: (1) cram at the end (2) study reasonably throughout the whole course (3) try to keep re-learning the course indefinitely.
We've thought long and hard about how we can cater to these different styles and think we've done a good job with a hybrid of #1 and 2. What would make more sense is something coming early next year as an option feature, which is inputting the date of the final exam of your course and then periodically adding in flashcards to a growing playlist that optimizes retention for the day of your exam. After you finish, you don't necessarily have to continue, but you could set a longer-retention date. An example of this would be that you have weekly quizzes and a final exam, and the algorithm could adjust the date for each quiz while balancing the overall arc towards the final.
