This sounds intriguing. I use Anki for Spanish now but have daydreamed about the power it could have for reading retention. It's always seemed daunting to figure out how to build a system to make this a smooth process but I guess these things are created brick by brick.
Consider doing a write up here on your system sometime? I'm sure many could get a ton of value from it.
Actually maybe I'll do a bounty post about this and try to crowdsource the methods stackers use for knowledge management. Seems like the problem of our time, how to best use the ridiculous amount of information we're all exposed to now.
