Despite a glut of reading recommendation engines, I still find that I rely on personal recommendations for 90% of the books that I read. Given that, I thought it might be useful to try to compile a list of prolific recommenders - people who provide a large number of reliable book recommendations.

I'll start off with the two obvious ones, Tyler Cowen and Cosma Shalizi. The LW/OB group of Eliezer, Robin Hanson, and Michael Vassar also provide useful recommendations (though much less frequently).

Who else can reliably recommend a good book?
