The flashcards app is not great. It can improve.

More serious comment.

It seems like there is less space (in our mind, and time) for yet another app. If you have this, vs youtube for course, people will still flock to youtube. Why don't you add the value that you are giving here by directly integrating or enhancing youtube. A chrome plugin or a youtube browser?

I really like the motivation behind this product. Learning is hard.
