Overdue no doubt about it, but anyway,
could we address in the same token the question that memes, in their initial
form can' t be broken up by crossovers !?
I mean, can we say that memes, by the ways we express them can 't be
broken !? That saying something nasty to somebody is an initial meme,
but that by the way we say it a crossover comes into being, a mutation
arises so that the chance of the meme's affecting its frequency rises or
decreases !?
In a sense I am saying that memes don 't have a fixed length dimension
when their meaning- fraction is concerned ! It is essential to their
survival
that certain ' replicator ' coding pieces, as I see ways of expressing some-
thing ( saying something nasty is different from saying something nice)
exists and come into being.
I think that such ways are the tools by which memes " instruct " us to get
them copied or not....
You do remerber something better if the way by which it is said to you
is useless, useful, harmful, acts upon certain emotions, etc....all what don
't
moves us, drifts away and gets forgotten.

Kenneth
