My friend, Sarah, from high school just had a piece published in Dialoguals, an online e-zine that publishes pieces that are ONLY dialogue: no "he said" "she replied" etc., no descriptions of settings, no descriptions of actions --- The stories contain nothing other than what is conveyed in the titles and in the dialogues.
They are ingenious very short literary pieces, typically no more than 300-400 words, that tell a story in a way that engages the reader.
I love Sarah's piece, "At the Bar". And the others there are good, too.
