Writing may not be produced for the prestiege of its result, but written words still serve an essential purpose for communication. I think that, as with any essential art, e.g. cooking, people will experiment with it to fit their needs.

Writing is also peculiar in that it is easily referenceable with a deep history, so it serves as a way to compare one's own ideas to others. Memes are similar in principle, but tend towards esotericism and ephemerality in a balkanized internet.
