I was hoping this one would show up. It's a startlingly simple paper, which both made the idea easy to implement (PageRank algorithm can be implemented in around 10 lines of Python, give or take), and easy to game (viz. the rise of link farms). Recommended for anyone with the prerequisite 1 semester of linear algebra or equivalent.
