"Biterature" is a combination, or portmanteau, of the words BITE (from sound bite for instance) and LITERATURE (written works). Biterature includes extremely short stories, quotes and thoughts... and is becoming more common as social web sites like Twitter become more popular. As the attention span of the average human reduces to almost nothing, people will only be able to read biterature, having lost the ability to read an entire page of text. Human speech will also change, with people talking in sound bites instead of full sentences.
The biterature of the great advertising copywriters of the mid-twentieth century is very popular in 2053... as is the biterature of early Twitter authors and thinkers.
