Ah, feic. It's Cornell format notes - for some reason I keep calling it Cambridge, I don't know why. Google Cornell Note Taking System, and learn it; if you ever have to take notes at a conference, seminar, lecture, meeting, phone call or anything else where people are talking, it's the best method around.

This right here made the whole month of reading HN worthwhile. Thank you.

My pleasure. I just wish someone had shown me the cornell system before year one of college :(
