So we all have an idea of what memes are, we know that memes are ideas and trends that get repeated and passed down in a society's cultural memory, but this definition seems a little too broad by itself. If meeting this criteria of merely being passed down in cultural memory was enough to be a meme, then we would have to qualify such broad cultural artifacts as language, law, craft, and science all as memes, and I have yet to see the 'English' or 'Biology' meme entries appear on KYM.
I think there must be some other criteria beyond simply being repeated over time by some culture that causes an idea to be considered a meme. So what else is it? Perhaps a neccesary prerequisite to being a meme is that the idea has to be simple enough to be abstracted out of its original context (advice animals take a image and a basic idea and reapply it to new situations and contexts Ad Nauseum)
What do you think?
