Peter - no worries - cultural memes, even small ones, are salient points in any discussion such as this one. I'll be correcting the original essay to take this into account.
Ellis, just to make it clear to me.
Did you mean memes to be the plural of meme, a tonening imitation of the ancient Greek mimea which in itself means imitation, or rather, what is to be passed on and achieved by imitation, like cultural behaviour or traditional behaviour, all of which is not innate behaviour?
If so, this might well become the starting point for a completely new column, unless you or Peter Goldsbury decide, that this as a topic in itself has already been discussed elsewhere in abundance. Then, I would be interested in the wheres. Anyway, it will be no less interesting to see you incorporating these memes more explicitly into the existing essay and see them discussed in this context.
I'll be looking forward to it.
