The Interstitial Arts Foundation is a not-for-profit organization dedicated to the study, support, and promotion of interstitial art: literature, music, visual and performance art found in between categories and genres – art that crosses borders. 
Interstitiality made an audible stir this past week when Writing Excuses posted an interview author Mary Robinette Kowal conducted with IAF co-founders Ellen Kushner and Delia Sherman (click this link to read and to listen):
Ellen Kushner and Delia Sherman from the Interstitial Arts Foundation join Mary and Dan at World Fantasy to discuss things that fall into the gaps between the genres.
How do publishers, agents, and booksellers deal with titles that are speculative, but that cannot be easily categorized as science fiction, fantasy, horror, paranormal romance, steampunk, or one of the other readily shelvable genres? And how should authors approach writing such titles?
The post even offers a writing prompt:
Writing Prompt: Try to write something that doesn’t fit neatly into the genres you’re familiar with.
A lively discussion has ensued in the comments there. Please listen, read and add to it, either there or here. We’d love to know what you think.
