What I like is that I can look at the list of referenced previous posts, and see which posts I should read.
Did you construct these automatically, or by hand?
Automatically, If I did it by hand, it would have looked nicer. I'm working on this project again, so I hope to have some much more user friendly things coded soon. Ill make what you mentioned as well.
I have created a list of Overcoming Bias posts for Robin Hanson available here. Additionally, using the links inside each posts, I have created a set of graphs (available here) such that if post A has a link to post B, then there is an arc from B to A. Enjoy! (There are also ones for Eliezer here).
