I only had one one set theory course so can't vouch for the details, but this seemed like a well done article on a subject that could easily have been more eyeglazingly superficial or obscure.
Much of my research on number theory and primality relies on a deep understanding in axiomatic set theory. Based on other news sites I've read that attempt to cover naive set theory, I was pleasantly surprised at the article's fairly decent coverage on the topic.
