The Millions posts a nice overview of some on-line fiction that David Backer has found. Some of it looks genre shaping, others such as Words Without Borders are more traditional literary reviews. The article is sure to have something for all tastes.
First, look Ben White’s Nanoism. White is a medical school student in Austin who’s developing the quality and presentation of twitter-sized fiction (140 characters or less). This isn’t a new form of fiction: fragments have existed from Gilgamesh to Kafka. But now these small pieces of language have won a currency in our minute-to-minute lives, a chirping and ambient speech. Sites have come about to present these “litwits” (Escarp, Thaumatrope, Outshine, PicFic). The difference with White’s stuff, both his own writing and the writing he publishes, is that in it you can see the litwit taking shape as a valid form, shaped by our technology, for getting at the truth.
