I don't think Eliezer's Introduction to Bayes's Theorem should be on here. I seriously don't think it's that good. It labors its points, and after I read the whole thing I still didn't get that you could use it to judge between different hypotheses, which is pretty much the most amazing thing I've learned this year, incidentally.

However, his new version, which he's working on and I got to read when I volunteered as an illustrator briefly, is absolutely amazing. When he gets that one finished, it will deserve its place on this list.
