Like I said, I'm pretty sure that would rule out HPMoR (Harry might not explicitly join a rationality organization, but the story exists to promote them).
HPMoR has significant value as a standalone work of fiction. There's a lot of new creative work. It's possible to read HPMoR on fanfic.net without ever knowing that the author, "Lesswrong," is Eliezer Yudkowsky, or what his affiliation is with the Center for Applied Rationality. I'd say that's a far cry from Harry appearing in a breakfast cereal commercial.
Of course, I probably agree with you that it would be much easier to avoid making the distinction at all. I'm just trying to point out that, if someone insists on making the distinction, it's possible to draw the line exactly where I want it ;-).
