Finally I believe that HPMOR is a much better recruitment tool than the sequences. If someone starts reading HPMOR they get hooked on it and spend a lot of time being exposed to our memes.

Yes. The sequences are a toolkit. HPMOR evokes emotions.

No one would have ever given two hoots about Objectivism if Rand hadn't written novels and embedded her philosophy in them. Some people are moved by the fiction, and thereby associate with the memes.
