Although tangentially linked to in the article, David Robinson's Introduction to Empirical Bayes[1] is also an excellent resource. It deals primarily with beta-binomial distributions.
TL;DR: One blog post is for Rotten Tomatoes and the other is for Metacritic.
I really just wanted to point out another solid Empirical Bayes resource, as there's not that many about. Yours and David's make a good combination covering different cases.
