    Actually, #4 is VERY important, for it is significance, or meaning,
    that comprises a meme; that is what is propagated. Behaviors and
    discourse, the engines of imitation, MEAN something to those
    doing or saying them. A meme is the selfsame meme regardless
    of whether it is performed, spoken or written; it is not the code or
    carrier which matter (although one kind or another must obtain,
    which is of no consequence), but the content; that is, memetic
    identity is a matter of semantics and pragmatics, not syntactics.
