I always find it interesting that say if someone asked me to describer every article I read on HN in a day I wouldn't be able to but if conversations with friends come up where each of them were relevant I'm usually able to describe there point of view and information and detail. Also it's similar with studying, I will go through the material and write all the key points down. I won't actually read them again, unless I forget something relevant later in study. I find in the exam when I'm given a relevant question I have near perfect recall on what I've studied no matter how large the amount of knowledge that I've gone through in a couple of days.
