So I've resubmitted to publications that had previously rejected one of my stories. I sent them new ones. Why? Well, for one, the story I sent in was kind of... an experimental piece. One big internal dialogue, really. But mainly it's because they read it and had something to say on it.
The rejection notice had a little something in there more than "We're going to pass on this one". One wrote me saying the character was very believable (score!), but it was mostly world building and exposition. Little action. And I agree; the story was just something I came up with while listening to Rocket Man on the radio. Another one told me that it fit too comfortably into the sci-fi genre, and their magazine is more of a subsection deal. Fair enough.
I read a few stories on one of them - Ideomancer - and thought "Yes. Yes, I can do this. This is good shit they've got up. My stuff belongs here. So I sent 'em another one I wrote. Dear Lord, let them read it and think the same thing.
So editors, keep the personalized notices coming. I'm going to feed on your recognition that I've written something like some kind of nerdy genre author vampire. I von to read your rejection.
