You do exclusives? So far I've been studiously avoiding anyone who wants an exclusive.
But I'm thinking why bother giving anyone an exclusive?
I mean if you get the offer from them then YAY. If you don't then so what?
If by some twist of fate you get an offer after you'd accepted some place else, then hey, it's just one editor that's mildly pissed at you and probably won't even remember your name in a week.
Short story market. Most don't accept simsubs, but they get back to you much faster than novel publishers. I always have a few stories out there, so it's not a big deal. And I don't want any editors even mildly pissed off at me.
