Looks like my latest Anki sprint has died out for now. I started building the deck at the start of December 2013, and did daily reviews until two weeks ago when I got fed up. I was trying to learn easy stuff like historical dates by adding them to Anki and then trying to learn them as they popped up as questions. I hadn't been adding much to the deck since mid-January, and the annoyance of random questions popping up about things I'd stopped thinking about got to be too much.

I was happy with keeping the deck in a text file though. I'll probably be reusing the technique and some of the current deck when I find something I want to start studying with Anki again.
