I don't see how cards would help me with mathematical ideas. You have to get them on a fundamental level, and then they're hard to forget. I'm more likely to forget the name of the theorem. But space repetition might be useful for formulas.
But I'm not too crazy about spaced repetition. I used it to learn all the capitals in the world, and after about a month I managed to do all of them without error. But after two years of barely using the knowledge, I only remember half.
Of course, I could keep reviewing it every few months to keep it fresh, but that's just not an efficient system, when you think of how many things I'm supposed to (and do) remember.
For me, at least, the best way to remember things is by tying them in as many associations and metaphors as I can, and that gives me a pretty reliable recall. It has some downsides: It's a bit more work than spaced repetition (requires creativity, for example), and it's not that good for unconnected data (but then, are random facts that useful anyway?). But I think that as a long-term method, it's much more solid.
I have had reasonable success using spaced repetition with math proofs (written in LaTeX). I create cards sparingly, often based on questions from problem sets which I shouldn't have gotten incorrect (i.e. the mistake stems from a fundamental misunderstanding of concepts, not a misstep in algebraic manipulation)

I find it too easy to trick myself into believing I understand a concept on a fundamental level. But often that "understanding" slips away, and six months later when faced with an example problem out of context I struggle to solve it.
