When I was teaching I'd love to ask a person to give me an explanation of a technical concept as though I was a 13 year old. It's easy to memorize the acronyms but it's much harder to unpack them, especially with enough understanding to simplify them for people that have no assumptions with respect to the concept.

Ryan Tomayko, in this case, has done an amazing thing: read along as he explains REST to his wife (who we may assume as an intelligent but non-technical person).
