I myself am extremely excited about the idea of a new Pulp Era. It was, actually my motivation to start publishing.
I used to love reading the Rex Stout mystery novelettes that were three to a book (Trio for Blunt Instruments, Three for the Chair, titles like that).
I have a bunch of things that I want to write shorter than the print industry likes. Including some serials. Right now I've got to figure out what to do with the sequel to Wife of Freedom. It's a longer book, and it has a decent breaking point about two thirds of the way through (and the last third needs the most work). But at the same time, there's a really satisfying arc to a couple of the characters that would work better in one story.
Sigh, well, when I'm done writing the mystery, I guess I'll throw myself into that.
