I thought self-teaching, self-taught, and similar were jargon that has been around for a long time. In the historically recent programming community especially it's all over the place: people who never did formal CS education teaching themselves how to program and are as or more effective than their Stanford peers. The difference between self-teach and learn is that the former is an attempt at learning through one's own will and direction, and the latter is merely a state of understanding the path to which can be from many directions (self-directed, teacher-directed, or just simple observation of the world around you).
