Oh, +1 to everything; this can't and shouldn't be the END, it's only an (educational, pedagogical) START.

And in fact, I think that one of the reasons the academic writing is getting better is because we've made that start: we don't have to start every essay with "So, what IS a vid?" You can move the discourse ON A BIT now that we're writing for an audience -even a non fan audience--who has SEEN more than one vid.
