Unless I've misread these companies, I don't quite think Medium and Quora are aiming for the same thing. Medium is more of a creative platform for storytellers (fiction) while Quora is more of a factual platform for information (non-fiction). That's not to say Medium couldn't have non-fiction as well, just as bloggers could write about fiction and non-fiction on the same blog, though bloggers tend to stick with one format or the other within the same site.
