> I think we should pass a hacker news law via referendum (that's a thing, right? It should be!) that any article mentioning quaternions must also generalize to Octonions ….

Given how much weirder octonions are than quaternions, I think that's mainly a recipe for not learning the most interesting things about quaternions. I'd rather hear about the connections between octonions and exceptional groups on one hand, and let quaternions be good at what they're good at on the other hand, and let the twain meet only as circumstances dictate.
