Ilya Somin, a native of Leningrad, has some interesting posts on communism. This is in the Volokh Conspiracy. The latest is on the evils of communism and the usefulness of review. It was very interesting that the current I guess prime minister there, Medyadev, has announced an effort to vie some institutional recognition to the victims in the former USSR. Earlier Somin had a post of the evils of Trotsky that I was late to comment on.
