I was wondering about the usefulness of spaced repetition for language (both natural and programming). I thought of analyzing a language for how frequently tokens appear in it (or vocabulary for a human language) and then prioritizing those cards first, and making them appear more frequently... then I realized, reality already does that for you, automatically! (On the other hand, Pimsleur is great, and taking a systematic approach to "100%ing" the "core" of a language is probably a great idea.)
