A couple of very interesting discussions on getting short fiction published on this podcast at Adventures in Sci-Fi Publishing:

Heinlein's rules of writing are debated, in particular the controversial third rule: 'You must refrain from re-writing, except to editorial order'.
Then there's a very ennervating discussion with Ferrett Steinmetz on how he got his short fiction established, via what he learned at the Clarion workshop.
Anyone who's trying to break into short fiction publishing will get a lot out of this podcast, I think.
