He's not. He's just returning a single document, which is the one with the largest value of created_at. IMO that's a pretty reasonable thing to do, because it's not unbounded expansion: the largest reduce value will be the largest single document in the database. Note that we explicitly say it's OK to emit an entire document as a value in a k/v index, i.e. emit(null, doc), and his reduce function is just picking one of those 'values'. Regards, Brian.
