Though notes in a Spaced repetition memory system are atomic in the same way as Evergreen notes (Evergreen notes should be atomic), they’re in many ways too atomized (Traditional spaced repetition memory prompts are atomized). The form discourages incremental synthesis and distillation.
The questions float in an undifferentiated mist, detached from any intrinsically meaningful context and not linked to relevant neighbors (Evergreen notes should be densely linked), and not especially meant to be accessed except within the review experience. They’re not meant to be durable, growing units; they’re meant to be disposable flotsam. All this could be fine, if they had a clear relationship with a separate system for Evergreen notes, but they don’t.
Happily: The mnemonic medium can be extended to one’s personal notes.

I start to identify open problems, questions that I’d personally like answered, but which don’t yet seem to have been answered. I identify tricks, observations that seem pregnant with possibility, but whose import I don’t yet know. And, sometimes, I identify what seem to me to be field-wide blind spots. I add questions about all these to Anki as well. In this way, Anki is a medium supporting my creative research. It has some shortcomings as such a medium, since it’s not designed with supporting creative work in mind – it’s not, for instance, equipped for lengthy, free-form exploration inside a scratch space.
The prompts in a Spaced repetition memory system are an unordered, unstructured set. Each prompt is intentionally quite fine-grained and atomic, since that’s what seems to work best for effective memorization ((Spaced repetition memory prompts should usually focus on one atomic unit). But this lack of structure creates a feeling of wandering through a forest, able to see only one leaf at a time.
In some domains, this type of atomization is appropriate. For instance, if you’re studying hiragana, or a large set of foreign-language vocabulary, the inter-prompt structure may not be terribly meaningful—you really do have a huge sack of atoms to memorize.
But in other domains—say, physics or math—the atoms only have meaning as part of a broader structure. When prompts in these domains work well, I suspect it’s because they’re hanging on some invisible, broader structure that’s already in the reviewer’s head.
This atomization is the primary reason that Spaced repetition memory prompts alone are a poor communications medium. It also limits their suitability for long-term personal notes: Existing spaced repetition systems discourage evergreen notes.
