I also have seen Keith Devlin in person but what impresses me most is that his real interest is selfinterest in media stuff. He lives at Stanford and the Stanford math faculty (that wrote the California Mathematics Content Standards, including foundational mathematics computational competence) has no idea what he is doing because he never darkens their door.
