I tend to side with the Bookkeeping alternative. I think on the same level as memes are a new form of communication that depends on new conditions (the internet and its framing of subject relation - the "wow that is LITERALLY me" effect), they're the resurfacing of what id call communicative "needs" that have existed for ages, culturally. I think the cut-up/remix model of memes for example is not so different from the kinds of instincts or desires that would have lead someone to, say, plunderphonic music, mail-art, relay novels, fanfiction or what have you.
WITH THAT SAID, the idea of memory is a topic i am very interested in on basically all fields i encounter, so that may be just me retrofitting it into broader theories on art lol.
I do find the idea of taking a non-standardized concept like memes into a laboratory-like condition to be very compelling!
