I think spaced repetition is over-hyped and under-understood. In language learning, it can have some benefit, but I think duolingo's approach, which does not obsess over computing repetition times, more effective than flash card software. I found that in order to use a new word, 6 repetitions isn't enough, you rather need a few hundreds to make it stick. Also waiting a few weeks until the next repetition is just a waste of time...
