You are guilty (like pretty much everyone else who ever uses the term meme
of perpetuating the myth that Dawkins invented the concept and name of a
meme.
In fact as Dawkins points out in "The Selfish Gene" and many susequent books is that the idea had been around for a while before. Unfortunatly I cant quite remember who did think of it.
On the contrary, the memes described in the book are smaller still to closely parallel the size of genes.
