You probably understand the relationship well enough, though -- even if that understanding comes from other vids rather than the show itself -- for Say to be meaningful. Maybe that's true for other sophisticated vid-watchers, too, so it probably isn't a very good example at all :)

So maybe the theory needs expansion to include the idea that even if you don't watch the source of a particular fandom, watching a lot of vids in it over a period of years can itself increase your reading level in the fandom. Which is kind of interesting...
