Referring back to MY explanation, I would still 
say that the design elements of the cover are only 
effective if the layout of the cover mimics a 
memetic pattern which has been shown to be viable. 
 As such, the content of the book would be a 
"mutation" of the cover and the content would be 
the viral form of the graphic meme.  On the other 
hand, the content of the book might be considered 
the "meme" (though I have some problem with this). 
 
So it might be better to say that the thesis 
statement is the meme and the "mutation" of this 
thesis occurs in a way which organizes random 
ideas such that they [as "padding" to the story] 
elicit the emotions of the reader... and so the 
reader might become attracted by the viral content 
of the book, and so replicate the theme.  
So we might consider the book to be the virus and 
the cover to act as a "hook" (similar to how the 
content, itself, [as virus] acts as a "hook" for 
the memetic "theme").  Then, the similarities 
between graphic design and viral hook might stand. 
 This would be explained (according to my analogy) 
as an emotional attachment to the design elements 
by which the content of the book is generalized to 
an (perhaps singular) element of the book which is 
suggested by, but not resolvable to, the design 
itself.
