The Memetic Bottleneck
Like a panel in a highly networked version of the Infinite Canvas, every meme is both a potential bottleneck and a possible choice. Since the sense that every meme has a preceding meme is essential to the appreciation of memes, the memetic bottleneck works in the inverse direction of the narrative bottleneck, generating potential pasts. To choose a meme to post is to choose which game to play with the audience. More significantly, it is to choose which save file to load up: it's scenario editing of history, conditioned on current mood.
