"What constitutes an unpublishable work? It could be many things: too long, too experimental, too dull; too exciting; it could be a work of juvenilia or a style you've long since discarded; it could be a work that falls far outside the range of what you're best known for; it could be a guilty pleasure or it could simply be that the world judges it to be awful, but you think is quite good. We've all got a folder full of things that would otherwise never see the light of day."

A great interview with the founder of the wonderful UbuWeb.
