One thing I figure I can do to help is to make the proposed terminology as polished as possible. In my original memetic hitchhiking article I used the term 'payload' to describe content that spread via memetic linkage with another meme. That seems reasonable if the context is already memetic hitchhiking - but otherwise it is too vague. Enter hitchhiking memes:
"Hitchhiking meme" definition: a meme which spreads primarily via memetic linkage to another meme.
Meme-savvy marketers are probably the #1 audience for the memetic hitchhiking concept. It is a common marketing technique to link a brand or product with some viral content to help distribute it. The basic idea of memetic hitchhiking is pretty obvious, but the terminology to describe it scientifically is not getting used. My hope is that the idea of hitchhiking memes will give memetic hitchhiking a boost.
